• Nginx location issue

  - by dave

  I'm trying to set a longer (30 day) 'expires' header for my (images only) in the /misc-stuff/ directory. This is what I'm using for my site : # Serve static files directly from nginx location ~* \.(jpg|jpeg|gif|png|bmp|ico|pdf|flv|swf|exe|html|htm|txt|css|js) { add_header Cache-Control public; add_header Cache-Control must-revalidate; expires 7d; } I want to be able to keep that code in to handle regular site images, but create a new block to handle the /misc-stuff/ directory. I have tried : location ^~ /misc-stuff/ { ... } The problem I'm having now is that my backup .php files in that directory show up as plain text if someone tries to access it. How do I set it up so ONLY .gif images in the /misc-stuff/ directory are effected?

• Wireless internet connection connects but internet does not work (no packets received). Wired does.

  - by Rodney

  When I connect my PC via ethernet cable to my ADSL router it works fine. When I connect via Wireless it connects and the internet will work for a random amount of time and then stop working. It stays connected with a strong signal but no packets are received. My laptop/iphone are right next to it and wireless works fine. If I open the Wireless USB status, it says it is connected to my SSID with full strength (54 mps - I am 3 meteres away from my router) and the activty shows as Packets 594 SENT and 105 RECEIVED (this goes up VERY slowly) I have tried the following: Turned off anitvirus and firewall completely. Tested the wifi signal- I am writing this on my laptop which is next to my PC and also has full wifi strength. Tried a different wireless adapter - I dug out an old PCI wireless card - it does the exact same thing. Compared all wireless settings to my laptop. I can ping google.com and it replies (sometimes with packet loss) When I reboot the PC it will connect for a minute or two (random time) and then just stops again. I tried Firefox, IE etc. no joy I have updated all latest versions (Netgear WG111v2) and drivers Checked Event Log - nothing unusual Ping the router (and even connect as admin for the few minutes when the internet does work) Changed the MTU down to 1200 using DrTCP Checked Device Manager for conflicts - none. I ping the router from the PC (192.168.0.10 - 192.168.0.1) and it replies with 4 packets. BUT, on my router admin page (which I access via http on my laptop wirelessly) - if I ping 192.168.0.10 all packets timeout (pinging my laptop 192.168.0.12 works fine) My router admin page shows the leased IP address for 192.168.0.10 (ie it is definitely talking to the router initially) Now I am out of ideas - please help. I think it is an OS/Software issue as I have tried 2 different wireless adapaters (PCI and USB) with the same result but all other wireless devices work fine around mine). It's not the firewall. It is getting assigned an IP address correctly (my PC gets 192.168.0.10, my laptop is .12) It is assigned by DHCP. As soon as I plug in the ethernet cable it all works fine. Repairing the adapter sometimes helps but it will always stop working after a random time. The wireless adapter always shows as connected with Excellent signal but the internet does not work. I am running Windows XP SP3 and have tried a Netgear WG111v2 USB adapter. Thanks in advance! UPDATE: The internet seems to be working, it is just either sending packets too small or slow to work (some small pages load bits of them very slowly but then hang). XP seems to have a networking diagnostic app - here is the output: Last diagnostic run time: 08/30/10 08:16:38 IP Configuration Diagnostic Invalid IP address info Valid IP address detected: 192.168.0.10 IP Layer Diagnostic Corrupted IP routing table info The default route is valid info The loopback route is valid info The local host route is valid info The local subnet route is valid Invalid ARP cache entries action The ARP cache has been flushed Gateway Diagnostic Gateway info The following proxy configuration is being used by IE: Automatically Detect Settings:Disabled Automatic Configuration Script: Proxy Server: Proxy Bypass list: info This computer has the following default gateway entry(ies): 192.168.0.1 info This computer has the following IP address(es): 192.168.0.10 info The default gateway is in the same subnet as this computer info The default gateway entry is a valid unicast address info The default gateway address was resolved via ARP in 1 try(ies) info The default gateway was reached via ICMP Ping in 1 try(ies) info TCP port 80 on host 65.55.12.249 was successfully reached info The Internet host www.microsoft.com was successfully reached info The default gateway is OK DNS Client Diagnostic DNS - Not a home user scenario info Using Web Proxy: no info Resolving name ok for (www.microsoft.com): yes No DNS servers DNS failure HTTP, HTTPS, FTP Diagnostic HTTP, HTTPS, FTP connectivity info FTP (Passive): Successfully connected to ftp.microsoft.com. info HTTP: Successfully connected to www.microsoft.com. warn HTTPS: Error 12002 connecting to www.microsoft.com: The operation timed out warn HTTPS: Error 12002 connecting to www.passport.net: The operation timed out error Could not make an HTTPS connection. info Redirecting user to support call WinSock Diagnostic WinSock status info All base service provider entries are present in the Winsock catalog. info The Winsock Service provider chains are valid. info Provider entry MSAFD Tcpip [TCP/IP] passed the loopback communication test. info Provider entry MSAFD Tcpip [UDP/IP] passed the loopback communication test. info Provider entry RSVP UDP Service Provider passed the loopback communication test. info Provider entry RSVP TCP Service Provider passed the loopback communication test. info Connectivity is valid for all Winsock service providers.

• Why isn't this rewrite rule (nginx) applied? (trying to setup Wordpress multisite)

  - by Brian Park

  Hi, I'm trying to setup Wordpress multisite (subfolder structure) with nginx, but having a problem with this rewrite rule. Below is the Apache's .htaccess, which I have to translate into nginx configuration. RewriteEngine On RewriteBase /blogs/ RewriteRule ^index\.php$ - [L] # uploaded files RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L] # add a trailing slash to /wp-admin RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L] RewriteCond %{REQUEST_FILENAME} -f [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^ - [L] RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L] RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L] RewriteRule . index.php [L] Below is what I came up with: server { listen 80; server_name example.com; server_name_in_redirect off; expires 1d; access_log /srv/www/example.com/logs/access.log; error_log /srv/www/example.com/logs/error.log; root /srv/www/example.com/public; index index.html; try_files $uri $uri/ /index.html; # rewriting uploaded files rewrite ^/blogs/(.+/)?files/(.+) /blogs/wp-includes/ms-files.php?file=$2 last; # add a trailing slash to /wp-admin rewrite ^/blogs/(.+/)?wp-admin$ /blogs/$1wp-admin/ permanent; if (!-e $request_filename) { rewrite ^/blogs/(.+/)?(wp-(content|admin|includes).*) /blogs/$2 last; rewrite ^/blogs/(.+/)?(.*\.php)$ /blogs/$2 last; } location /blogs/ { index index.php; #try_files $uri $uri/ /blogs/index.php?q=$uri&$args; } location ~ \.php$ { include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/www/example.com/public$fastcgi_script_name; } # static assets location ~* ^.+\.(manifest)$ { access_log /srv/www/example.com/logs/static.log; } location ~* ^.+\.(ico|ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ { # only set expires max IFF the file is a static file and exists if (-f $request_filename) { expires max; access_log /srv/www/example.com/logs/static.log; } } } In the above code, I believe rewrite ^/blogs/(.+/)?(.*\.php)$ /blogs/$2 last; has no effect because when I look at the access_log file, I see the following line: 2010/09/15 01:14:55 [error] 10166#0: *8 "/srv/www/example.com/public/blogs/test/index.php" is not found (2: No such file or directory), request: "GET /blogs/test/ HTTP/1.1" (Here, 'test' is the second blog created using multisite feature) What I'm expecting is that /blogs/test/index.php gets rewritten to /blogs/index.php, but it doesn't seem to do that... Am I overlooking something obvious? Thanks!

• Why is Windows 7 announcing itself as an IPv6 router?

  - by Paul

  I have a 6in4 ipv6 connection from a linux box to a broker. I use gogoc to establish the connection to the broker, and radvd to advertise the route to clients on the network. All this appears to work, the problem is that I have a Windows 7 machine on the same network, and it is advertising itself as a ipv6 router. Which it is not. This is output from radvdump: # # radvd configuration generated by radvdump 1.8.5 # based on Router Advertisement from [snip]:ea2 # received by interface eth0 # interface eth0 { AdvSendAdvert on; # Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump AdvManagedFlag on; AdvOtherConfigFlag on; AdvReachableTime 0; AdvRetransTimer 0; AdvCurHopLimit 0; AdvDefaultLifetime 1800; AdvHomeAgentFlag off; AdvDefaultPreference medium; AdvSourceLLAddress on; AdvLinkMTU 1500; }; # End of interface definition # # radvd configuration generated by radvdump 1.8.5 # based on Router Advertisement from [snip]:1121 # received by interface eth0 # interface eth0 { AdvSendAdvert on; # Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump AdvManagedFlag off; AdvOtherConfigFlag off; AdvReachableTime 0; AdvRetransTimer 0; AdvCurHopLimit 64; AdvDefaultLifetime 1800; AdvHomeAgentFlag off; AdvDefaultPreference medium; AdvLinkMTU 1280; AdvSourceLLAddress on; prefix [snip]::/64 { AdvValidLifetime 86400; AdvPreferredLifetime 14400; AdvOnLink on; AdvAutonomous on; AdvRouterAddr off; }; # End of prefix definition }; # End of interface definition And I end up with two routes: $ ip -6 route [snip]::/64 dev eth0 proto kernel metric 256 expires 86117sec fe80::/64 dev eth0 proto kernel metric 256 default via [snip]:ea2 dev eth0 proto kernel metric 1024 expires 1492sec default via [snip]:1121 dev eth0 proto kernel metric 1024 expires 1506sec The ea2 route is to the Windows7 box. It doesn't have a router installed, and doesn't have any tun/tap interfaces. I can't see why it is doing this. I could disable ipv6 on it, but I want it to be a client, not a router. Update: The IP Helper service (Provides tunnel connectivity using IPv6 transition technologies (6to4, ISATAP, Port Proxy, and Teredo), and IP-HTTPS. If this service is stopped, the computer will not have the enhanced connectivity benefits that these technologies offer.) seems to be the culprit, as if it is stopped, I don't get the routes advertised. So my question is now more specifically "why is IP Helper announcing routes?".

• Nginx + PHP-FPM on Centos 6.5 gives me 502 Bad Gateway (fpm error: unable to read what child say: Bad file descriptor)

  I am setting up a standard LEMP stack.

• Nginx, proxy passing to Apache, and SSL

  - by Vic

  I have Nginx and Apache set up with Nginx proxy-passing everything to Apache except static resources. I have a server set up for port 80 like so: server { listen 80; server_name *.example1.com *.example2.com; [...] location ~* \.(?:ico|css|js|gif|jpe?g|png|pdf|te?xt)$ { access_log off; expires max; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; add_header Vary: Accept-Encoding; } location / { proxy_pass http://127.0.0.1:8080; include /etc/nginx/conf.d/proxy.conf; } } And since we have multiple ssl sites (with different ssl certificates) I have a server{} block for each of them like so: server { listen 443 ssl; server_name *.example1.com; [...] location ~* \.(?:ico|css|js|gif|jpe?g|png|pdf|te?xt)$ { access_log off; expires max; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; add_header Vary: Accept-Encoding; } location / { proxy_pass https://127.0.0.1:8443; include /etc/nginx/conf.d/proxy.conf; proxy_set_header X-Forwarded-Port 443; proxy_set_header X-Forwarded-Proto https; } } server { listen 443 ssl; server_name *.example2.com; [...] location ~* \.(?:ico|css|js|gif|jpe?g|png|pdf|te?xt)$ { access_log off; expires max; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; add_header Vary: Accept-Encoding; } location / { proxy_pass https://127.0.0.1:8445; include /etc/nginx/conf.d/proxy.conf; proxy_set_header X-Forwarded-Port 443; proxy_set_header X-Forwarded-Proto https; } } First of all, I think there is a very obvious problem here, which is that I'm double-encrypting everything, first at the nginx level and then again by Apache. To make everything worse, I just started using Amazon's Elastic Load Balancer, so I added the certificate to the ELB and now SSL encryption is happening three times. That's gotta be horrible for performance. What is the sane way to handle this? Should I be forwarding https on the ELB - http on nginx - http on apache? Secondly, there is so much duplication above. Is the best method to not repeat myself to put all of the static asset handling in an include file and just include it in the server?

• SSL Certificate Expiry: Does the expiry time make any difference at all?

  - by CYMR0

  I need to know when an SSL certificate actually expires. Does it just look at the expiry date, or does it also take into account the expiry time? Let's say a certificate expired on 1/1/2013 at 11am. Does that certificate expire at 11:01am or is it only the following day that the certificate expires? I have been told both are true. Hope that makes sense! Our suppliers messed up and let our certificate expire, and I'm trying to figure out how much compensation we're owed. I found this question Details on exact expiration datetime of an SSL certificate? but it didn't quite answer what I need (and I didn't like to revive a dead question).

• Serving a default image with nginx

  - by ustun

  I have the following configuration in nginx: location /static/ { root /srv/kose/; expires 2w; access_log off; } location / { proxy_pass http://127.0.0.1:8089; } If a file is not found in /static/, I want to serve a default image, and not proxy_pass to 8089. Currently, it looks for the file in the root for static, if it cannot find it, it tries the proxy. I have tried the following, but it doesn't work. How can I tell nginx to serve the default image? I have also tried try_files to no avail. location /static/ { root /srv/kose/; expires 2w; access_log off; error_page 404 /srv/static/defaultimage.jpg; } location / { proxy_pass http://127.0.0.1:8089; }

• kSOAP2 and SOAPAction on Android

  - by Matze

  Hi everyone, I am trying to access a Webservice with kSOAP2 on an Android Phone. I think the connection is being established, but the server won't answer my request since I'm not providing a SOAP Action Header which seems to be required in SOAP Version 1.1(please correct me if I'm wrong here) which I have to use since the server does not support Version 1.2 . The concrete Faultcode which is returning in the request looks like this: faultactor null faultcode "S:Server" (id=830064966432) faultstring "String index out of range: -11" (id=830064966736) The errorcode which is generated on the server (I'm running it on a localhost) looks like this: 4.05.2010 20:20:29 com.sun.xml.internal.ws.transport.http.HttpAdapter fixQuotesAroundSoapAction WARNUNG: Received WS-I BP non-conformant Unquoted SoapAction HTTP header: http://server.contextlayer.bscwi.de/createContext 24.05.2010 20:20:29 com.sun.xml.internal.ws.server.sei.EndpointMethodHandler invoke SCHWERWIEGEND: String index out of range: -11 java.lang.StringIndexOutOfBoundsException: String index out of range: -11 at java.lang.String.substring(Unknown Source) at de.bscwi.contextlayer.xml.XmlValidator.isValid(XmlValidator.java:41) at de.bscwi.contextlayer.server.ContextWS.createContext(ContextWS.java:45) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.sun.xml.internal.ws.api.server.InstanceResolver$1.invoke(Unknown Source) at com.sun.xml.internal.ws.server.InvokerTube$2.invoke(Unknown Source) at com.sun.xml.internal.ws.server.sei.EndpointMethodHandler.invoke(Unknown Source) at com.sun.xml.internal.ws.server.sei.SEIInvokerTube.processRequest(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.__doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber._doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.runSync(Unknown Source) at com.sun.xml.internal.ws.server.WSEndpointImpl$2.process(Unknown Source) at com.sun.xml.internal.ws.transport.http.HttpAdapter$HttpToolkit.handle(Unknown Source) at com.sun.xml.internal.ws.transport.http.HttpAdapter.handle(Unknown Source) at com.sun.xml.internal.ws.transport.http.server.WSHttpHandler.handleExchange(Unknown Source) at com.sun.xml.internal.ws.transport.http.server.WSHttpHandler.handle(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.AuthFilter.doFilter(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.ServerImpl$Exchange$LinkHandler.handle(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.ServerImpl$Exchange.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) The relevant part of the WSDL (at least that's what I'm thinking) looks like this: <operation name="createContext"> <soap:operation soapAction=""/> - <input> <soap:body use="literal" namespace="http://server.contextlayer.bscwi.de/"/> </input> - <output> <soap:body use="literal" namespace="http://server.contextlayer.bscwi.de/"/> </output> </operation> In my code I'm adding a Header, but it seems like I'm doing it wrong: private static final String SOAP_ACTION = ""; //... SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope (SoapEnvelope.VER11); soapEnvelope.setOutputSoapObject(Request); AndroidHttpTransport aht = new AndroidHttpTransport (URL); //... aht.call(SOAP_ACTION, soapEnvelope); SoapPrimitive resultString = (SoapPrimitive) soapEnvelope.getResponse(); Any advice would be great since I'm running out of ideas.. Thanks folks!

• HOWTO: disable jmx in activemq network of brokers (spring, xbean)

  - by subes

  Since I've struggled a lot with this problem, I am posting my solution. Disabling jmx in an activemq network of brokers removes race conditions about the registration of the jmx connector. When starting multiple activemq servers on the same machine: Failed to start jmx connector: Cannot bind to URL [rmi://localhost:1099/jmxrmi]: javax.naming.NameAlreadyBoundException: jmxrmi [Root exception is java.rmi.AlreadyBoundException: jmxrmi] Another problem with this is, that even if you don't cause a race condition, this exception can still occur. Even when starting one broker after another while waiting for them to initialize properly in between. If one process is run by root as the first instance and the other as a normal user, somehow the user process tries to register its own jmx connector, though there already is one. Or another exception which happens when the broker that successfully registered the jmx connector goes down: Failed to start jmx connector: Cannot bind to URL [rmi://localhost:1099/jmxrmi]: javax.naming.ServiceUnavailableException [Root exception is java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: java.net.ConnectException: Connection refused] Those exceptions cause the network of brokers to stop working, or to not work at all. The trick to disable jmx was, that jmx had to be disabled in the connectionfactory aswell. The documentation http://activemq.apache.org/jmx.html does not say that this is needed explicitly. So I had to struggle for 2 days until I found the solution: <beans xmlns="http://www.springframework.org/schema/beans" xmlns:amq="http://activemq.apache.org/schema/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core-5.3.1.xsd"> <!-- Spring JMS Template --> <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate"> <constructor-arg ref="connectionFactory" /> </bean> <!-- Caching, sodass das jms template überhaupt nutzbar ist in sachen performance --> <bean id="connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> <constructor-arg ref="amqConnectionFactory" /> <property name="exceptionListener" ref="jmsExceptionListener" /> <property name="sessionCacheSize" value="1" /> </bean> <!-- Jeder Client verbindet sich mit seinem eigenen broker, broker sind untereinander vernetzt. Nur wenn hier nochmals jmx deaktiviert wird, bleibt es auch deaktiviert... --> <amq:connectionFactory id="amqConnectionFactory" brokerURL="vm://broker:default?useJmx=false" /> <!-- Broker suchen sich einen eigenen Port und sind gegenseitig verbunden, ergeben dadurch ein Grid. Dies zwar etwas langsamer, aber dafür ausfallsicherer. Siehe http://activemq.apache.org/networks-of-brokers.html --> <amq:broker useJmx="false" persistent="false"> <!-- Wird benötigt um JMX endgültig zu deaktivieren --> <amq:managementContext> <amq:managementContext connectorHost="localhost" createConnector="false" /> </amq:managementContext> <!-- Nun die normale Konfiguration für Network of Brokers --> <amq:networkConnectors> <amq:networkConnector networkTTL="1" duplex="true" dynamicOnly="true" uri="multicast://default" /> </amq:networkConnectors> <amq:persistenceAdapter> <amq:memoryPersistenceAdapter /> </amq:persistenceAdapter> <amq:transportConnectors> <amq:transportConnector uri="tcp://localhost:0" discoveryUri="multicast://default" /> </amq:transportConnectors> </amq:broker> With this, there is no need to specify -Dcom.sun.management.jmxremote=false for the jvm. Which somehow also didn't work for me, because the connectionfactory started the jmx connector.

• Replace JBoss error page with Axis2 fault XML response

  - by Dario

  I'm developing a webservice with Axis2 1.4.1 on JBoss 4.2.3/Tomcat 5.5.27 and Java 1.5.0 (15-b04). It works flawlessly but when an exception happens I get a JBoss error 500 HTML page instead of an Axis2 XML/SOAP fault. This behavoir is vexing, because it difficults to handle errors in the webservice client or in SoapUI while developing. Can I change this to get the SOAP fault? Maybe it's just an Axis2 or JBoss parameter, but I didn't find any clue about. EDIT: Here goes the new stacktrace: [ERROR] WSDoAllReceiver: security processing failed org.apache.axis2.AxisFault: WSDoAllReceiver: security processing failed at org.apache.rampart.handler.WSDoAllReceiver.processBasic(WSDoAllReceiver.java:214) at org.apache.rampart.handler.WSDoAllReceiver.processMessage(WSDoAllReceiver.java:86) at org.apache.rampart.handler.WSDoAllHandler.invoke(WSDoAllHandler.java:72) at org.apache.axis2.engine.Phase.invoke(Phase.java:317) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:264) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:163) at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:275) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:133) at javax.servlet.http.HttpServlet.service(HttpServlet.java:647) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:875) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595) Caused by: org.apache.ws.security.WSSecurityException: The security token could not be authenticated or authorized at org.apache.ws.security.processor.UsernameTokenProcessor.handleUsernameToken(UsernameTokenProcessor.java:155) at org.apache.ws.security.processor.UsernameTokenProcessor.handleToken(UsernameTokenProcessor.java:53) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:311) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:228) at org.apache.rampart.handler.WSDoAllReceiver.processBasic(WSDoAllReceiver.java:211) ... 23 more [ERROR] Servlet.service() para servlet AxisServlet lanzó excepción java.lang.NullPointerException at org.apache.rampart.RampartMessageData.<init>(RampartMessageData.java:308) at org.apache.rampart.MessageBuilder.build(MessageBuilder.java:61) at org.apache.rampart.handler.RampartSender.invoke(RampartSender.java:64) at org.apache.axis2.engine.Phase.invoke(Phase.java:317) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:264) at org.apache.axis2.engine.AxisEngine.sendFault(AxisEngine.java:520) at org.apache.axis2.transport.http.AxisServlet.handleFault(AxisServlet.java:416) at org.apache.axis2.transport.http.AxisServlet.processAxisFault(AxisServlet.java:379) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:167) at javax.servlet.http.HttpServlet.service(HttpServlet.java:647) at javax.servlet.http.HttpServlet.service(HttpServlet.java:729) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:174) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:875) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595) EDIT 2: After giving the bounty I found that I was wrong about 1.2.9-SNAPSHOT version of Axiom.

• Smart auto detect and replace URLs with anchor tags

  - by Robert Koritnik

  I've written a regular expression that automatically detects URLs in free text that users enter. This is not such a simple task as it may seem at first. Jeff Atwood writes about it in his post. His regular expression works, but needs extra code after detection is done. I've managed to write a regular expression that does everything in a single go. This is how it looks like (I've broken it down into separate lines to make it more understandable what it does): 1 (?<outer>\()? 2 (?<scheme>http(?<secure>s)?://)? 3 (?<url> 4 (?(scheme) 5 (?:www\.)? 6 | 7 www\. 8 ) 9 [a-z0-9] 10 (?(outer) 11 [-a-z0-9/+&@#/%?=~_()|!:,.;cšžcd]+(?=\)) 12 | 13 [-a-z0-9/+&@#/%?=~_()|!:,.;cšžcd]+ 14 ) 15 ) 16 (?<ending>(?(outer)\))) As you may see, I'm using named capture groups (used later in Regex.Replace()) and I've also included some local characters (cšžcd), that allow our localised URL to be parsed as well. You can easily omit them if you'd like. Anyway. Here's what it does (referring to line numbers): 1 - detects if URL starts with open braces (is contained inside braces) and stores it in "outer" named capture group 2 - checks if it starts with URL scheme also detecting whether scheme is SSL or not 3 - starts parsing URL itself (will store it in "url" named capture group) 4-8 - if statement that says: if "sheme" was present then www. part is optional, otherwise mandatory for a string to be a link (so this regular expression detects all strings that start with either http or www) 9 - first character after http:// or www. should be either a letter or a number (this can be extended if you would like to cover even more links, but I've decided to omit other characters because I can't remember a link that would start with some other character 10-14 - if statement that says: if "outer" (braces) was present capture everything up to the last closing braces otherwise capture all 15 - closes the named capture group for URL 16 - if open braces was present, capture closing braces as well and store it in "ending" named capture group First and last line used to have \s* in them as well, so user could also write open braces and put a space inside before pasting link. Anyway. My code that does link replacement with actual anchor HTML elements looks exactly like this: value = Regex.Replace( value, @"(?<outer>\()?(?<scheme>http(?<secure>s)?://)?(?<url>(?(scheme)(?:www\.)?|www\.)[a-z0-9](?(outer)[-a-z0-9/+&@#/%?=~_()|!:,.;cšžcd]+(?=\))|[-a-z0-9/+&@#/%?=~_()|!:,.;cšžcd]+))(?<ending>(?(outer)\)))", "${outer}<a href=\"http${secure}://${url}\">http${secure}://${url}</a>${ending}", RegexOptions.Compiled | RegexOptions.CultureInvariant | RegexOptions.IgnoreCase); As you can see I'm using named capture groups to replace link with an Anchor tag: ${outer}<a href=\"http${secure}://${url}\">http${secure}://${url}</a>${ending} I could as well omit the http(s) part in anchor display to make links look friendlier, but for now I decided not to. Question I would like for my links to be replaced with shortenings as well. So when user copies a very long links (for instance if they would copy a link from google maps that usually generates long links I would like to shorten the visible part of the anchor tag. Link would work, but visible part of an anchor tag would be shortened to some number of characters. Does the replace string support notations like that so I can stil use a singe Regex.Replace() call?

• news feed using .Net Dataservices / OData / Atom ?

  - by Stephan

  Let's say I have an web CMS type application, and an EDM model with an entity called 'article', and I need to offer the ability for client applications, to a read/query the articles (and other resources stored in our database) a straightforward syndication feed of these articles to end users (along the lines of a simple RSS feed) It seems to me that for the first task, and .net 4's dataservice would be perfect for the job. For the second case, I'm wondering (a) whether atom the right format to choose - I think it is - and (b) whether it's possible to achieve such a feed using the same ado.net OData service. I took a look at some of the examples out there and briefly set up a proof of concept: http://localhost/projectname/DataService.svc/Articles <?xml version="1.0" encoding="utf-8" standalone="yes"?> <feed xml:base="http://localhost/projectname/DataService.svc/" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://www.w3.org/2005/Atom"> <title type="text">Articles</title> <id>http://localhost/projectname/DataService.svc/Articles</id> <updated>2010-05-21T09:41:22Z</updated> <link rel="self" title="Articles" href="Articles" /> <entry> <id>http://---------DataService.svc/Articles(1)</id> <title type="text"></title> <updated>2010-05-21T09:41:22Z</updated> <author> <name /> </author> <link rel="edit" title="Article" href="Articles(1)" /> <category term="Model1.Article" scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" /> <content type="application/xml"> <m:properties> <d:int_ContentID m:type="Edm.Int32">1</d:int_ContentID> <d:Titel>hello world</d:Titel> <d:Source>http://www.google.com</d:Source> </m:properties> </content> </entry> </feed> and noticed that, though the feed works and items are showing up, the title tag on the entry level is left blank. (as a result, when you check this feed in a feed reader, you will see no title). I searched msdn but haven't found a way to do that, but it should be possible. Stackoverflow itself uses an atom feed in that fashion, so it should be possible. Right? So I suppose my question is; Is there a way to make the ado.net dataservice Atom feed look like something suitable for your average news feed reader? - OR, am I using the wrong tool for the wrong purposes, and should I be looking elsewhere (.net syndication API's perhaps)?

• JSON posting, am i pushing JSON too far?

  - by joe90

  Im just wondering if I am pushing JSON too far? and if anyone has hit this before? I have a xml file: <?xml version="1.0" encoding="UTF-8"?> <customermodel:Customer xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:customermodel="http://customermodel" xmlns:personal="http://customermodel/personal" id="1" age="1" name="Joe"> <bankAccounts xsi:type="customermodel:BankAccount" accountNo="10" bankName="HSBC" testBoolean="true" testDate="2006-10-23" testDateTime="2006-10-23T22:15:01+08:00" testDecimal="20.2" testTime="22:15:01+08:00"> <count>0</count> <bankAddressLine>HSBC</bankAddressLine> <bankAddressLine>London</bankAddressLine> <bankAddressLine>31 florence</bankAddressLine> <bankAddressLine>Swindon</bankAddressLine> </bankAccounts> </customermodel:Customer> Which contains elements and attributes.... Which when i convert to JSON gives me: {"customermodel:Customer":{"id":"1","name":"Joe","age":"1","xmlns:xsi":"http://www.w3.org/2001/XMLSchema-instance","bankAccounts":{"testDate":"2006-10-23","testDecimal":"20.2","count":"0","testDateTime":"2006-10-23T22:15:01+08:00","bankAddressLine":["HSBC","London","31 florence","Swindon"],"testBoolean":"true","bankName":"HSBC","accountNo":"10","xsi:type":"customermodel:BankAccount","testTime":"22:15:01+08:00"},"xmlns:personal":"http://customermodel/personal","xmlns:customermodel":"http://customermodel"}} So then i send this too the client.. which coverts to a js object (or whatever) edits some values (the elements) and then sends it back to the server. So i get the JSON string, and convert this back into XML: <customermodel:Customer> <id>1</id> <age>1</age> <name>Joe</name> <xmlns:xsi>http://www.w3.org/2001/XMLSchema-instance</xmlns:xsi> <bankAccounts> <testDate>2006-10-23</testDate> <testDecimal>20.2</testDecimal> <testDateTime>2006-10-23T22:15:01+08:00</testDateTime> <count>0</count> <bankAddressLine>HSBC</bankAddressLine> <bankAddressLine>London</bankAddressLine> <bankAddressLine>31 florence</bankAddressLine> <bankAddressLine>Swindon</bankAddressLine> <accountNo>10</accountNo> <bankName>HSBC</bankName> <testBoolean>true</testBoolean> <xsi:type>customermodel:BankAccount</xsi:type> <testTime>22:15:01+08:00</testTime> </bankAccounts> <xmlns:personal>http://customermodel/personal</xmlns:personal> <xmlns:customermodel>http://customermodel</xmlns:customermodel> </customermodel:Customer> And there is the problem, is doesn't seem to know the difference between elements/attributes so i can not check against a XSD to check this is now valid? Is there a solution to this? I cannot be the first to hit this problem?

Here's what it does (referring to line numbers): 1 - detects if URL starts with open braces (is contained inside braces) and stores it in "outer" named capture group 2 - checks if it starts with URL scheme also detecting whether scheme is SSL or not 3 - start parsing URL itself (will store it in "url" named capture group) 4-8 - if statement that says: if "sheme" was present then www. part is optional, otherwise mandatory for a string to be a link (so this regular expression detects all strings that start with either http or www) 9 - first character after http:// or www. should be either a letter or a number (this can be extended if you'd like to cover even more links, but I've decided not to because I can't think of a link that would start with some obscure character) 10-14 - if statement that says: if "outer" (braces) was present capture everything up to the last closing braces otherwise capture all 15 - closes the named capture group for URL 16 - if open braces were present, capture closing braces as well and store it in "ending" named capture group First and last line used to have \s* in them as well, so user could also write open braces and put a space inside before pasting link. Anyway. My code that does link replacement with actual anchor HTML elements looks exactly like this: value = Regex.Replace( value, @"(?<outer>\()?(?<scheme>http(?<secure>s)?://)?(?<url>(?(scheme)(?:www\.)?|www\.)[a-z0-9](?(outer)[-a-z0-9/+&@#/%?=~_()|!:,.;cšžcd]+(?=\))|[-a-z0-9/+&@#/%?=~_()|!:,.;cšžcd]+))(?<ending>(?(outer)\)))", "${outer}<a href=\"http${secure}://${url}\">http${secure}://${url}</a>${ending}", RegexOptions.Compiled | RegexOptions.CultureInvariant | RegexOptions.IgnoreCase); As you can see I'm using named capture groups to replace link with an Anchor tag: "${outer}<a href=\"http${secure}://${url}\">http${secure}://${url}</a>${ending}" I could as well omit the http(s) part in anchor display to make links look friendlier, but for now I decided not to. Question I would like my links to be replaced with shortenings as well. So when user copies a very long link (for instance if they would copy a link from google maps that usually generates long links) I would like to shorten the visible part of the anchor tag. Link would work, but visible part of an anchor tag would be shortened to some number of characters. I could as well append ellipsis at the end of at all possible (and make things even more perfect). Does Regex.Replace() method support replacement notations so that I can still use a single call? Something similar as string.Format() method does when you'd like to format values in string format (decimals, dates etc...).

• Can I create an xml that specifies element from 2 nested xsd's without using a prefixes?

  - by TweeZz

  I have 2 xsd's which are nested: DefaultSchema.xsd: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="DefaultSchema" targetNamespace="http://myNamespace.com/DefaultSchema.xsd" elementFormDefault="qualified" xmlns="http://myNamespace.com/DefaultSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" > <xs:complexType name="ZForm"> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="Part" minOccurs="0" maxOccurs="unbounded" type="Part"/> </xs:sequence> <xs:attribute name="Title" use="required" type="xs:string"/> <xs:attribute name="Version" type="xs:int"/> </xs:complexType> <xs:complexType name="Part"> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="Label" type="Label" minOccurs="0"></xs:element> </xs:sequence> <xs:attribute name="Title" use="required" type="xs:string"/> </xs:complexType> <xs:complexType name="Label"> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute name="Title" type="xs:string"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:schema> ExportSchema.xsd: (this one kinda wraps 1 more element (ZForms) around the main element (ZForm) of the DefaultSchema) <?xml version="1.0" encoding="utf-8"?> <xs:schema id="ExportSchema" targetNamespace="http://myNamespace.com/ExportSchema.xsd" elementFormDefault="qualified" xmlns="http://myNamespace.com/DefaultSchema.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:es="http://myNamespace.com/ExportSchema.xsd" > <xs:import namespace="http://myNamespace.com/DefaultSchema.xsd" schemaLocation="DefaultSchema.xsd"/> <xs:element name="ZForms" type="es:ZFormType"></xs:element> <xs:complexType name="ZFormType"> <xs:sequence> <xs:element name="ZForm" type="ZForm" maxOccurs="unbounded" /> </xs:sequence> </xs:complexType> </xs:schema> And then finally I have a generated xml: <?xml version="1.0" encoding="utf-8"?> <ZForms xmlns="http://myNamespace.com/ExportSchema.xsd"> <ZForm Version="1" Title="FormTitle"> <Part Title="PartTitle" > <Label Title="LabelTitle" /> </Part> </ZForm> </ZForms> Visual studio complains it doesn't know what 'Part' is. I was hoping I do not need to use xml namespace prefixes (..) to make this xml validate, since ExportSchema.xsd has a reference to the DefaultSChema.xsd. Is there any way to make that xml structure valid without explicitly specifying the DefaultSchema.xsd? Or is this a no go?

• ASP.NET GZip Encoding Caveats

  - by Rick Strahl

  GZip encoding in ASP.NET is pretty easy to accomplish using the built-in GZipStream and DeflateStream classes and applying them to the Response.Filter property.  While applying GZip and Deflate behavior is pretty easy there are a few caveats that you have watch out for as I found out today for myself with an application that was throwing up some garbage data. But before looking at caveats let’s review GZip implementation for ASP.NET. ASP.NET GZip/Deflate Basics Response filters basically are applied to the Response.OutputStream and transform it as data is written to it through the ASP.NET Response object. So a Response.Write eventually gets written into the output stream which if a filter is also written through the filter stream’s interface. To perform the actual GZip (and Deflate) encoding typically used by Web pages .NET includes the GZipStream and DeflateStream stream classes which can be readily assigned to the Repsonse.OutputStream. With these two stream classes in place it’s almost trivially easy to create a couple of reusable methods that allow you to compress your HTTP output. In my standard WebUtils utility class (from the West Wind West Wind Web Toolkit) created two static utility methods – IsGZipSupported and GZipEncodePage – that check whether the client supports GZip encoding and then actually encodes the current output (note that although the method includes ‘Page’ in its name this code will work with any ASP.NET output). /// <summary> /// Determines if GZip is supported /// </summary> /// <returns></returns> public static bool IsGZipSupported() { string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"]; if (!string.IsNullOrEmpty(AcceptEncoding) && (AcceptEncoding.Contains("gzip") || AcceptEncoding.Contains("deflate"))) return true; return false; } /// <summary> /// Sets up the current page or handler to use GZip through a Response.Filter /// IMPORTANT: /// You have to call this method before any output is generated! /// </summary> public static void GZipEncodePage() { HttpResponse Response = HttpContext.Current.Response; if (IsGZipSupported()) { string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"]; if (AcceptEncoding.Contains("deflate")) { Response.Filter = new System.IO.Compression.DeflateStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); Response.Headers.Remove("Content-Encoding"); Response.AppendHeader("Content-Encoding", "deflate"); } else { Response.Filter = new System.IO.Compression.GZipStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); Response.Headers.Remove("Content-Encoding"); Response.AppendHeader("Content-Encoding", "gzip"); } } } As you can see the actual assignment of the Filter is as simple as: Response.Filter = new DeflateStream(Response.Filter, System.IO.Compression.CompressionMode.Compress); which applies the filter to the OutputStream. You also need to ensure that your response reflects the new GZip or Deflate encoding and ensure that any pages that are cached in Proxy servers can differentiate between pages that were encoded with the various different encodings (or no encoding). To use this utility function now is trivially easy: In any ASP.NET code that wants to compress its Response output you simply use: protected void Page_Load(object sender, EventArgs e) { WebUtils.GZipEncodePage(); Entry = WebLogFactory.GetEntry(); var entries = Entry.GetLastEntries(App.Configuration.ShowEntryCount, "pk,Title,SafeTitle,Body,Entered,Feedback,Location,ShowTopAd", "TEntries"); if (entries == null) throw new ApplicationException("Couldn't load WebLog Entries: " + Entry.ErrorMessage); this.repEntries.DataSource = entries; this.repEntries.DataBind(); } Here I use an ASP.NET page, but the above WebUtils.GZipEncode() method call will work in any ASP.NET application type including HTTP Handlers. The only requirement is that the filter needs to be applied before any other output is sent to the OutputStream. For example, in my CallbackHandler service implementation by default output over a certain size is GZip encoded. The output that is generated is JSON or XML and if the output is over 5k in size I apply WebUtils.GZipEncode(): if (sbOutput.Length > GZIP_ENCODE_TRESHOLD) WebUtils.GZipEncodePage(); Response.ContentType = ControlResources.STR_JsonContentType; HttpContext.Current.Response.Write(sbOutput.ToString()); Ok, so you probably get the idea: Encoding GZip/Deflate content is pretty easy. Hold on there Hoss –Watch your Caching Or is it? There are a few caveats that you need to watch out for when dealing with GZip content. The fist issue is that you need to deal with the fact that some clients don’t support GZip or Deflate content. Most modern browsers support it, but if you have a programmatic Http client accessing your content GZip/Deflate support is by no means guaranteed. For example, WinInet Http clients don’t support GZip out of the box – it has to be explicitly implemented. Other low level HTTP clients on other platforms too don’t support GZip out of the box. The problem is that your application, your Web Server and Proxy Servers on the Internet might be caching your generated content. If you return content with GZip once and then again without, either caching is not applied or worse the wrong type of content is returned back to the client from a cache or proxy. The result is an unreadable response for *some clients* which is also very hard to debug and fix once in production. You already saw the issue of Proxy servers addressed in the GZipEncodePage() function: // Allow proxy servers to cache encoded and unencoded versions separately Response.AppendHeader("Vary", "Content-Encoding"); This ensures that any Proxy servers also check for the Content-Encoding HTTP Header to cache their content – not just the URL. The same thing applies if you do OutputCaching in your own ASP.NET code. If you generate output for GZip on an OutputCached page the GZipped content will be cached (either by ASP.NET’s cache or in some cases by the IIS Kernel Cache). But what if the next client doesn’t support GZip? She’ll get served a cached GZip page that won’t decode and she’ll get a page full of garbage. Wholly undesirable. To fix this you need to add some custom OutputCache rules by way of the GetVaryByCustom() HttpApplication method in your global_ASAX file: public override string GetVaryByCustomString(HttpContext context, string custom) { // Override Caching for compression if (custom == "GZIP") { string acceptEncoding = HttpContext.Current.Response.Headers["Content-Encoding"]; if (string.IsNullOrEmpty(acceptEncoding)) return ""; else if (acceptEncoding.Contains("gzip")) return "GZIP"; else if (acceptEncoding.Contains("deflate")) return "DEFLATE"; return ""; } return base.GetVaryByCustomString(context, custom); } In a page that use Output caching you then specify: <%@ OutputCache Duration="180" VaryByParam="none" VaryByCustom="GZIP" %> To use that custom rule. It’s all Fun and Games until ASP.NET throws an Error Ok, so you’re up and running with GZip, you have your caching squared away and your pages that you are applying it to are jamming along. Then BOOM, something strange happens and you get a lovely garbled page that look like this: Lovely isn’t it? What’s happened here is that I have WebUtils.GZipEncode() applied to my page, but there’s an error in the page. The error falls back to the ASP.NET error handler and the error handler removes all existing output (good) and removes all the custom HTTP headers I’ve set manually (usually good, but very bad here). Since I applied the Response.Filter (via GZipEncode) the output is now GZip encoded, but ASP.NET has removed my Content-Encoding header, so the browser receives the GZip encoded content without a notification that it is encoded as GZip. The result is binary output. Here’s what Fiddler says about the raw HTTP header output when an error occurs when GZip encoding was applied: HTTP/1.1 500 Internal Server Error Cache-Control: private Content-Type: text/html; charset=utf-8 Date: Sat, 30 Apr 2011 22:21:08 GMT Content-Length: 2138 Connection: close ?`I?%&/m?{J?J??t??` … binary output striped here Notice: no Content-Encoding header and that’s why we’re seeing this garbage. ASP.NET has stripped the Content-Encoding header but left our filter intact. So how do we fix this? In my applications I typically have a global Application_Error handler set up and in this case I’ve been using that. One thing that you can do in the Application_Error handler is explicitly clear out the Response.Filter and set it to null at the top: protected void Application_Error(object sender, EventArgs e) { // Remove any special filtering especially GZip filtering Response.Filter = null; … } And voila I get my Yellow Screen of Death or my custom generated error output back via uncompressed content. BTW, the same is true for Page level errors handled in Page_Error or ASP.NET MVC Error handling methods in a controller. Another and possibly even better solution is to check whether a filter is attached just before the headers are sent to the client as pointed out by Adam Schroeder in the comments: protected void Application_PreSendRequestHeaders() { // ensure that if GZip/Deflate Encoding is applied that headers are set // also works when error occurs if filters are still active HttpResponse response = HttpContext.Current.Response; if (response.Filter is GZipStream && response.Headers["Content-encoding"] != "gzip") response.AppendHeader("Content-encoding", "gzip"); else if (response.Filter is DeflateStream && response.Headers["Content-encoding"] != "deflate") response.AppendHeader("Content-encoding", "deflate"); } This uses the Application_PreSendRequestHeaders() pipeline event to check for compression encoding in a filter and adjusts the content accordingly. This is actually a better solution since this is generic – it’ll work regardless of how the content is cleaned up. For example, an error Response.Redirect() or short error display might get changed and the filter not cleared and this code actually handles that. Sweet, thanks Adam. It’s unfortunate that ASP.NET doesn’t natively clear out Response.Filters when an error occurs just as it clears the Response and Headers. I can’t see where leaving a Filter in place in an error situation would make any sense, but hey - this is what it is and it’s easy enough to fix as long as you know where to look. Riiiight! IIS and GZip I should also mention that IIS 7 includes good support for compression natively. If you can defer encoding to let IIS perform it for you rather than doing it in your code by all means you should do it! Especially any static or semi-dynamic content that can be made static should be using IIS built-in compression. Dynamic caching is also supported but is a bit more tricky to judge in terms of performance and footprint. John Forsyth has a great article on the benefits and drawbacks of IIS 7 compression which gives some detailed performance comparisons and impact reviews. I’ll post another entry next with some more info on IIS compression since information on it seems to be a bit hard to come by.

• May 2011 Release of the Ajax Control Toolkit

  - by Stephen Walther

  I’m happy to announce that the Superexpert team has published the May 2011 release of the Ajax Control Toolkit at CodePlex. You can download the new release at the following URL: http://ajaxcontroltoolkit.codeplex.com/releases/view/65800 This release focused on improving the ModalPopup and AsyncFileUpload controls. Our team closed a total of 34 bugs related to the ModalPopup and AsyncFileUpload controls. Enhanced ModalPopup Control You can take advantage of the Ajax Control Toolkit ModalPopup control to easily create popup dialogs in your ASP.NET Web Forms applications. When the dialog appears, you cannot interact with any page content which appears behind the modal dialog. For example, the following page contains a standard ASP.NET Button and Panel. When you click the Button, the Panel appears as a popup dialog: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Simple.aspx.vb" Inherits="ACTSamples.Simple" %> <%@ Register TagPrefix="act" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Simple Modal Popup Sample</title> <style type="text/css"> html { background-color: blue; } #dialog { border: 2px solid black; width: 500px; background-color: White; } #dialogContents { padding: 10px; } .modalBackground { background-color:Gray; filter:alpha(opacity=70); opacity:0.7; } </style> </head> <body> <form id="form1" runat="server"> <div> <act:ToolkitScriptManager ID="tsm" runat="server" /> <asp:Panel ID="dialog" runat="server"> <div id="dialogContents"> Here are the contents of the dialog. <br /> <asp:Button ID="btnOK" Text="OK" runat="server" /> </div> </asp:Panel> <asp:Button ID="btnShow" Text="Open Dialog" runat="server" /> <act:ModalPopupExtender TargetControlID="btnShow" PopupControlID="dialog" OkControlID="btnOK" DropShadow="true" BackgroundCssClass="modalBackground" runat="server" /> </div> </form> </body> </html>     Notice that the page includes two controls from the Ajax Control Toolkit: the ToolkitScriptManager and the ModalPopupExtender control. Any page which uses any of the controls from the Ajax Control Toolkit must include a ToolkitScriptManager. The ModalPopupExtender is used to create the popup. The following properties are set: · TargetControlID – This is the ID of the Button or LinkButton control which causes the modal popup to be displayed. · PopupControlID – This is the ID of the Panel control which contains the content displayed in the modal popup. · OKControlID – This is the ID of a Button or LinkButton which causes the modal popup to close. · DropShadow – Displays a drop shadow behind the modal popup. · BackgroundCSSClass – The name of a Cascading Style Sheet class which is used to gray out the background of the page when the modal popup is displayed. The ModalPopup is completely cross-browser compatible. For example, the following screenshots show the same page displayed in Firefox 4, Internet Explorer 9, and Chrome 11: The ModalPopup control has lots of nice properties. For example, you can make the ModalPopup draggable. You also can programmatically hide and show a modal popup from either server-side or client-side code. To learn more about the properties of the ModalPopup control, see the following website: http://www.asp.net/ajax/ajaxcontroltoolkit/Samples/ModalPopup/ModalPopup.aspx Animated ModalPopup Control In the May 2011 release of the Ajax Control Toolkit, we enhanced the Modal Popup control so that it supports animations. We made this modification in response to a feature request posted at CodePlex which got 65 votes (plenty of people wanted this feature): http://ajaxcontroltoolkit.codeplex.com/workitem/6944 I want to thank Dani Kenan for posting a patch to this issue which we used as the basis for adding animation support for the modal popup. Thanks Dani! The enhanced ModalPopup in the May 2011 release of the Ajax Control Toolkit supports the following animations: OnShowing – Called before the modal popup is shown. OnShown – Called after the modal popup is shown. OnHiding – Called before the modal popup is hidden. OnHidden – Called after the modal popup is hidden. You can use these animations, for example, to fade-in a modal popup when it is displayed and fade-out the popup when it is hidden. Here’s the code: <act:ModalPopupExtender ID="ModalPopupExtender1" TargetControlID="btnShow" PopupControlID="dialog" OkControlID="btnOK" DropShadow="true" BackgroundCssClass="modalBackground" runat="server"> <Animations> <OnShown> <Fadein /> </OnShown> <OnHiding> <Fadeout /> </OnHiding> </Animations> </act:ModalPopupExtender>     So that you can experience the full joy of this animated modal popup, I recorded the following video: Of course, you can use any of the animations supported by the Ajax Control Toolkit with the modal popup. The animation reference is located here: http://www.asp.net/ajax/ajaxcontroltoolkit/Samples/Walkthrough/AnimationReference.aspx Fixes to the AsyncFileUpload In the May 2011 release, we also focused our energies on performing bug fixes for the AsyncFileUpload control. We fixed several major issues with the AsyncFileUpload including: It did not work in master pages It did not work when ClientIDMode=”Static” It did not work with Firefox 4 It did not work when multiple AsyncFileUploads were included in the same page It generated markup which was not HTML5 compatible The AsyncFileUpload control is a super useful control. It enables you to upload files in a form without performing a postback. Here’s some sample code which demonstrates how you can use the AsyncFileUpload: <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Simple.aspx.vb" Inherits="ACTSamples.Simple1" %> <%@ Register TagPrefix="act" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="server"> <title>Simple AsyncFileUpload</title> </head> <body> <form id="form1" runat="server"> <div> <act:ToolkitScriptManager ID="tsm" runat="server" /> User Name: <br /> <asp:TextBox ID="txtUserName" runat="server" /> <asp:RequiredFieldValidator EnableClientScript="false" ErrorMessage="Required" ControlToValidate="txtUserName" runat="server" /> <br /><br /> Avatar: <act:AsyncFileUpload ID="async1" ThrobberID="throbber" UploadingBackColor="yellow" ErrorBackColor="red" CompleteBackColor="green" UploaderStyle="Modern" PersistFile="true" runat="server" /> <asp:Image ID="throbber" ImageUrl="uploading.gif" style="display:none" runat="server" /> <br /><br /> <asp:Button ID="btnSubmit" Text="Submit" runat="server" /> </div> </form> </body> </html> And here’s the code-behind for the page above: Public Class Simple1 Inherits System.Web.UI.Page Private Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click If Page.IsValid Then ' Get Form Fields Dim userName As String Dim file As Byte() userName = txtUserName.Text If async1.HasFile Then file = async1.FileBytes End If ' Save userName, file to database ' Redirect to success page Response.Redirect("SimpleDone.aspx") End If End Sub End Class   The form above contains an AsyncFileUpload which has values for the following properties: ThrobberID – The ID of an element in the page to display while a file is being uploaded. UploadingBackColor – The color to display in the upload field while a file is being uploaded. ErrorBackColor – The color to display in the upload field when there is an error uploading a file. CompleteBackColor – The color to display in the upload field when the upload is complete. UploaderStyle – The user interface style: Traditional or Modern. PersistFile – When true, the uploaded file is persisted in Session state. The last property PersistFile, causes the uploaded file to be stored in Session state. That way, if completing a form requires multiple postbacks, then the user needs to upload the file only once. For example, if there is a server validation error, then the user is not required to re-upload the file after fixing the validation issue. In the sample code above, this condition is simulated by disabling client-side validation for the RequiredFieldValidator control. The RequiredFieldValidator EnableClientScript property has the value false. The following video demonstrates how the AsyncFileUpload control works: You can learn more about the properties and methods of the AsyncFileUpload control by visiting the following page: http://www.asp.net/ajax/ajaxcontroltoolkit/Samples/AsyncFileUpload/AsyncFileUpload.aspx Conclusion In the May 2011 release of the Ajax Control Toolkit, we addressed over 30 bugs related to the ModalPopup and AsyncFileUpload controls. Furthermore, by building on code submitted by the community, we enhanced the ModalPopup control so that it supports animation (Thanks Dani). In our next sprint for the June release of the Ajax Control Toolkit, we plan to focus on the HTML Editor control. Subscribe to this blog to keep updated.

• Azure Grid Computing - Worker Roles as HPC Compute Nodes

  - by JoshReuben

  Overview ·        With HPC 2008 R2 SP1 You can add Azure worker roles as compute nodes in a local Windows HPC Server cluster. ·        The subscription for Windows Azure like any other Azure Service - charged for the time that the role instances are available, as well as for the compute and storage services that are used on the nodes. ·        Win-Win ? - Azure charges the computer hour cost (according to vm size) amortized over a month – so you save on purchasing compute node hardware. Microsoft wins because you need to purchase HPC to have a local head node for managing this compute cluster grid distributed in the cloud. ·        Blob storage is used to hold input & output files of each job. I can see how Parametric Sweep HPC jobs can be supported (where the same job is run multiple times on each node against different input units), but not MPI.NET (where different HPC Job instances function as coordinated agents and conduct master-slave inter-process communication), unless Azure is somehow tunneling MPI communication through inter-WorkerRole Azure Queues. ·        this is not the end of the story for Azure Grid Computing. If MS requires you to purchase a local HPC license (and administrate it), what's to stop a 3rd party from doing this and encapsulating exposing HPC WCF Broker Service to you for managing compute nodes? If MS doesn’t  provide head node as a service, someone else will! Process ·        requires creation of a worker node template that specifies a connection to an existing subscription for Windows Azure + an availability policy for the worker nodes. ·        After worker nodes are added to the cluster, you can start them, which provisions the Windows Azure role instances, and then bring them online to run HPC cluster jobs. ·        A Windows Azure worker role instance runs a HPC compatible Azure guest operating system which runs on the VMs that host your service. The guest operating system is updated monthly. You can choose to upgrade the guest OS for your service automatically each time an update is released - All role instances defined by your service will run on the guest operating system version that you specify. see Windows Azure Guest OS Releases and SDK Compatibility Matrix (http://go.microsoft.com/fwlink/?LinkId=190549). ·        use the hpcpack command to upload file packages and install files to run on the worker nodes. see hpcpack (http://go.microsoft.com/fwlink/?LinkID=205514). Requirements ·        assuming you have an azure subscription account and the HPC head node installed and configured. ·        Install HPC Pack 2008 R2 SP 1 -  see Microsoft HPC Pack 2008 R2 Service Pack 1 Release Notes (http://go.microsoft.com/fwlink/?LinkID=202812). ·        Configure the head node to connect to the Internet - connectivity is provided by the connection of the head node to the enterprise network. You may need to configure a proxy client on the head node. Any cluster network topology (1-5) is supported). ·        Configure the firewall - allow outbound TCP traffic on the following ports: 80,       443, 5901, 5902, 7998, 7999 ·        Note: HPC Server  uses Admin Mode (Elevated Privileges) in Windows Azure to give the service administrator of the subscription the necessary privileges to initialize HPC cluster services on the worker nodes. ·        Obtain a Windows Azure subscription certificate - the Windows Azure subscription must be configured with a public subscription (API) certificate -a valid X.509 certificate with a key size of at least 2048 bits. Generate a self-sign certificate & upload a .cer file to the Windows Azure Portal Account page > Manage my API Certificates link. see Using the Windows Azure Service Management API (http://go.microsoft.com/fwlink/?LinkId=205526). ·        import the certificate with an associated private key on the HPC cluster head node - into the trusted root store of the local computer account. Obtain Windows Azure Connection Information for HPC Server ·        required for each worker node template ·        copy from azure portal - Get from: navigation pane > Hosted Services > Storage Accounts & CDN ·        Subscription ID - a 32-char hex string in the form xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. In Properties pane. ·        Subscription certificate thumbprint - a 40-char hex string (you need to remove spaces). In Management Certificates > Properties pane. ·        Service name - the value of <ServiceName> configured in the public URL of the service (http://<ServiceName>.cloudapp.net). In Hosted Services > Properties pane. ·        Blob Storage account name - the value of <StorageAccountName> configured in the public URL of the account (http://<StorageAccountName>.blob.core.windows.net). In Storage Accounts > Properties pane. Import the Azure Subscription Certificate on the HPC Head Node ·        enable the services for Windows HPC Server  to authenticate properly with the Windows Azure subscription. ·        use the Certificates MMC snap-in to import the certificate to the Trusted Root Certification Authorities store of the local computer account. The certificate must be in PFX format (.pfx or .p12 file) with a private key that is protected by a password. ·        see Certificates (http://go.microsoft.com/fwlink/?LinkId=163918). ·        To open the certificates snapin: Run > mmc. File > Add/Remove Snap-in > certificates > Computer account > Local Computer ·        To import the certificate via wizard - Certificates > Trusted Root Certification Authorities > Certificates > All Tasks > Import ·        After the certificate is imported, it appears in the details pane in the Certificates snap-in. You can open the certificate to check its status. Configure a Proxy Client on the HPC Head Node ·        the following Windows HPC Server services must be able to communicate over the Internet (through the firewall) with the services for Windows Azure: HPCManagement, HPCScheduler, HPCBrokerWorker. ·        Create a Windows Azure Worker Node Template ·        Edit HPC node templates in HPC Node Template Editor. ·        Specify: 1) Windows Azure subscription connection info (unique service name) for adding a set of worker nodes to the cluster + 2)worker node availability policy – rules for deploying / removing worker role instances in Windows Azure o   HPC Cluster Manager > Configuration > Navigation Pane > Node Templates > Actions pane > New à Create Node Template Wizard or Edit à Node Template Editor o   Choose Node Template Type page - Windows Azure worker node template o   Specify Template Name page – template name & description o   Provide Connection Information page – Azure Subscription ID (text) & Subscription certificate (browse) o   Provide Service Information page - Azure service name + blob storage account name (optionally click Retrieve Connection Information to get list of available from azure – possible LRT). o   Configure Azure Availability Policy page - how Windows Azure worker nodes start / stop (online / offline the worker role instance -  add / remove) – manual / automatic o   for automatic - In the Configure Windows Azure Worker Availability Policy dialog -select days and hours for worker nodes to start / stop. ·        To validate the Windows Azure connection information, on the template's Connection Information tab > Validate connection information. ·        You can upload a file package to the storage account that is specified in the template - eg upload application or service files that will run on the worker nodes. see hpcpack (http://go.microsoft.com/fwlink/?LinkID=205514). Add Azure Worker Nodes to the HPC Cluster ·        Use the Add Node Wizard – specify: 1) the worker node template, 2) The number of worker nodes   (within the quota of role instances in the azure subscription), and 3)           The VM size of the worker nodes : ExtraSmall, Small, Medium, Large, or ExtraLarge.  ·        to add worker nodes of different sizes, must run the Add Node Wizard separately for each size. ·        All worker nodes that are added to the cluster by using a specific worker node template define a set of worker nodes that will be deployed and managed together in Windows Azure when you start the nodes. This includes worker nodes that you add later by using the worker node template and, if you choose, worker nodes of different sizes. You cannot start, stop, or delete individual worker nodes. ·        To add Windows Azure worker nodes o   In HPC Cluster Manager: Node Management > Actions pane > Add Node à Add Node Wizard o   Select Deployment Method page - Add Azure Worker nodes o   Specify New Nodes page - select a worker node template, specify the number and size of the worker nodes ·        After you add worker nodes to the cluster, they are in the Not-Deployed state, and they have a health state of Unapproved. Before you can use the worker nodes to run jobs, you must start them and then bring them online. ·        Worker nodes are numbered consecutively in a naming series that begins with the root name AzureCN – this is non-configurable. Deploying Windows Azure Worker Nodes ·        To deploy the role instances in Windows Azure - start the worker nodes added to the HPC cluster and bring the nodes online so that they are available to run cluster jobs. This can be configured in the HPC Azure Worker Node Template – Azure Availability Policy -  to be automatic or manual. ·        The Start, Stop, and Delete actions take place on the set of worker nodes that are configured by a specific worker node template. You cannot perform one of these actions on a single worker node in a set. You also cannot perform a single action on two sets of worker nodes (specified by two different worker node templates). ·        ·          Starting a set of worker nodes deploys a set of worker role instances in Windows Azure, which can take some time to complete, depending on the number of worker nodes and the performance of Windows Azure. ·        To start worker nodes manually and bring them online o   In HPC Node Management > Navigation Pane > Nodes > List / Heat Map view - select one or more worker nodes. o   Actions pane > Start – in the Start Azure Worker Nodes dialog, select a node template. o   the state of the worker nodes changes from Not Deployed to track the provisioning progress – worker node Details Pane > Provisioning Log tab. o   If there were errors during the provisioning of one or more worker nodes, the state of those nodes is set to Unknown and the node health is set to Unapproved. To determine the reason for the failure, review the provisioning logs for the nodes. o   After a worker node starts successfully, the node state changes to Offline. To bring the nodes online, select the nodes that are in the Offline state > Bring Online. ·        Troubleshooting o   check node template. o   use telnet to test connectivity: telnet <ServiceName>.cloudapp.net 7999 o   check node status - Deployment status information appears in the service account information in the Windows Azure Portal - HPC queries this -  see  node status information for any failed nodes in HPC Node Management. ·        When role instances are deployed, file packages that were previously uploaded to the storage account using the hpcpack command are automatically installed. You can also upload file packages to storage after the worker nodes are started, and then manually install them on the worker nodes. see hpcpack (http://go.microsoft.com/fwlink/?LinkID=205514). ·        to remove a set of role instances in Windows Azure - stop the nodes by using HPC Cluster Manager (apply the Stop action). This deletes the role instances from the service and changes the state of the worker nodes in the HPC cluster to Not Deployed. ·        Each time that you start a set of worker nodes, two proxy role instances (size Small) are configured in Windows Azure to facilitate communication between HPC Cluster Manager and the worker nodes. The proxy role instances are not listed in HPC Cluster Manager after the worker nodes are added. However, the instances appear in the Windows Azure Portal. The proxy role instances incur charges in Windows Azure along with the worker node instances, and they count toward the quota of role instances in the subscription.
