  • How to configure Java Network Proxy Settings for domain computers

    - by adminParsed
    I need to set the Network Proxy Settings to Direct Connection, for computers on our domain. I have looked at the unattended setup configurations, as well as the deployment.properties file, and didn't see an option to set it to Direct Connection. Are there any alternate means to set this? ex...logon script, vbscript, powershell, GPO, (would be great, but I couldn't find anything on this) Thanks

  • How to update ADFS 2.0 Proxy Server Certificate?

    - by user167963
    I have proxy server that sits in the DMZ. The default site is running the adfs and has a certificate that is about to expire in 2 weeks. I am not sure what are steps involved in applying a new ssl certificate. I know at the least I will install the new certificate(s) in the local store. Go to IIS and change the certificate using the binding settings. Is there any othern place I have update the certificate?

  • From Monorail to ASP.Net MVC

    - by Cheekysoft
    The last time I took on a non-trivial .Net/C# application I used Castle Monorail and, on the whole, enjoyed the experience. Early-access/preview releases of .Net MVC were not yet available. Many "Microsoft shops" will now find the "official" solution more appealing. Has anyone gone from Monorail to .Net MVC. How did you find the switch? What are the biggest differences, presently?

  • What techniques are being used to pass MVC ModelState validation errors back to the client when usin

    - by Jon Erickson
    I'm sort of thinking out loud here, so let me know if I need to clarify... on ajax heavy sites, when using JsonResult to pass information back to the client, what techniques, patterns, best practices are being used to pass ModelState validation errors back to the client? I am using xVal and castle validation on my view models, is there some sort of standard to get jquery validate to display errors coming from ajax responses?

  • Is there any way to add references without recompiling in .NET?

    - by Jader Dias
    I am using a IoC Container (Castle Windsor) to instantiate classes accordingly to the configuration file. If I want to add classes from a new dll that didn't exist when I compiled the project, there is any way to do that without recompiling? Edit: As this project is a Service Host for WCF service, and the classes that I want to include after compilation are WCF Services I would like also to know if I can include endpoint information about new services without recompiling.

    - by zaph0d
    I am injecting HttpContextBase into a caching class. HttpContextBase is registered as PerWebRequest.

I understand that PerWebRequest does not work in Application_Start though: http://stackoverflow.com/questions/2670717/castle-perrequestlifestyle-not-recognize What is the best way to resolve this in my situation?

  • Apache SSLProxyMachineCertificateFile does not work

    - by Serge - appTranslator
    I'm setting up an Apache reverse proxy that exposes a client certificate to the remote host. I do it using SSLProxyMachineCertificateFile /etc/tls/pki/certandkey.pem Problem: The remote host does not recognize the client certificate. Notes: certandkey.pem contains the unencrypted key and the cert. from the proxy box, curl -E /etc/tls/pki/certandkey.pem https://www.remote.com works fine. It's a GoDaddy SSL certificate. It's bundled with a gd_bundle.crt. Should I use SSLProxyMachineCertificateChainFile? I'm on CentOS 6.3 with Apache 2.2.15 (SSLProxyMachineCertificateChainFile not available)

  • Apache internal test servers

    - by user74274
    I want to build a test system in the office. On one box I will install XAMPP. I will put a website that I want to test on that box. Now I do not want it connected to the Internet. So my plan is to use a reverse proxy to resolve things like ads and other external links. So I am thinking of using mod_proxy for that. Now my question is, How many boxes do I need? 1 for Xampp, 1 for mod_proxy and 1 for the server where mod proxy redirects them to. Total of three. But maybe I could do it with less. Can I run Mod_proxy on the first box? Is there a better way? Thanks

  • Tomcat cookies not working via my ProxyPass VirtualHost

    - by John
    Hi there. I'm having some issues with getting cookies to work when using a ProxyPass to redirect traffic on port 80 to a web-application hosted via Tomcat. My motivation for enabling cookies is to get rid of the "jsessionid=" parameter that is appended to the URLs. I've enabled cookies in my context.xml in META-INF/ for my web application. When I access the webapplication via http://url:8080/webapp it works as expected, the jsessionid parameter is not visible in the URL, instead it's stored in a cookie. When accessing my website via an apache2 virtualhost the cookies doesn't seem to work because now "jsessionid" is being appended to the URLs. How can I solve this issue? Here's my VHost configuration: <VirtualHost *:80 ServerName somedomain.no ServerAlias www.somedomain.no <Proxy * Order deny,allow Allow from all </Proxy ProxyPreserveHost Off ProxyPass / http://localhost:8080/webapp/ ProxyPassReverse / http://localhost:8080/webapp/ ErrorLog /var/log/apache2/somedomain.no.error.log CustomLog /var/log/apache2/somedomain.no.access.log combined </VirtualHost

  • TPROXY Not working with HAProxy, Ubuntu 14.04

    - by Nyxynyx
    I'm trying to use HAProxy as a fully transparent proxy using TPROXY in Ubuntu 14.04. HAProxy will be setup on the first server with eth1 111.111.250.250 and eth0 10.111.128.134. The single balanced server has eth1 and eth0 as well. eth1 is the public facing network interface while eth0 is for the private network which both servers are in. Problem: I'm able to connect to the balanced server's port 1234 directly (via eth1) but am not able to reach the balanced server via Haproxy port 1234 (which redirects to 1234 via eth0). Am I missing out something in this configuration?

  • Apache2 mod_proxy and post-multipart size

    - by Pietro
    Hi, I have Apache2 configured to proxy all traffic directed to a specific virtual host to a local tomcat instance. All is good and fine but for multipart posts larger than ~100kb. Such posts fail on the tomcat end with an exception like SocketTimeoutException. If I connect directly to Tomcat (which listens on a port != 80) then all posts are handled just fine. The Apache virtual host config goes like this: NameVirtualHost * SetOutputFilter DEFLATE <VirtualHost *> ServerName foo.bar.com ErrorLog c:/wamp/logs/foo_error.log CustomLog c:/wamp/logs/foo_access.log combined ProxyTimeout 60 ProxyPass / http://localhost:10080/foo/ ProxyPassReverse / http://localhost:10080/foo/ ProxyPassReverseCookieDomain localhost bar.com ProxyPassReverseCookiePath /foo / </VirtualHost> I tried browsing the Apache2 and mod_proxy docs but found nothing useful. Any idea why Apache2 refuses to proxy requests bigger than X bytes ? Thanks!

  • How to restrict Apache Location directive to cetain sub-domain?

    - by ohho
    On our server www.example.com, we use the <Location> directive to proxy traffic to a back-end server: <Location /app1> ProxyPass http://192.168.1.20 </Location> Then we added a sub-domain uat.example.com which points to the same IP address of www.example.com. We want to use it as a proxy for client to test an app being developed. Hopefully, the client can access via: http:/uat.example.com/app2_uat Now if we add a Location: <Location /app2_uat> ProxyPass http://192.168.1.30 </Location> The client can access both: http:/www.example.com/app2_uat http:/uat.example.com/app2_uat How can I restrict Location such that only: http:/uat.example.com/app2_uat is accessible? (i.e. http:/www.example.com/app2_uat should not be accessible.)

  • nginx regex characters that require quoting?

    - by Michael Louis Thaler
    So I was configuring nginx today and I hit a weird problem. I was trying to match a location like this: location ~ ^/([0-9]+)/(.*) { # do proxy redirects } ...for URLs like "http://my.domain.com/0001/index.html". This rule was never matching, despite the fact that it by all rights should. It took me awhile to figure out, based on this documentation, that some characters in regexes need to be quoted. The problem is, the documentation is for rewrites, and it specifically calls out curly braces, not square brackets. After a fair bit of experimentation that involved a lot of swearing, I discovered that I could fix the problem by quoting the regex like so: location ~ "^/([0-9]+)/(.*)" { # do proxy redirects } Is there a list somewhere of characters that nginx requires quoting regexes with? Or could there be something else going on here that I'm totally missing? This is my first nginx configuration job, so it's very possible I've misunderstood something...

  • Odd squid transparent redirect behavior

    - by EMiller
    This is the first time I've set up squid. It's running a redirect script that does some text search/replace on html pages, and then saves them to a location on the same machine on the nginx path - then issues the redirect to that URL (it's an art project :D). The relevant lines in squid.conf are http_port 3128 transparent redirect_program /etc/squid/jefferson_redirect.py The jefferson_redirect.py script is based on this script: http://gofedora.com/how-to-write-custom-redirector-rewritor-plugin-squid-python/ The issue: I'm getting strange http redirect behavior. For example, here is the normal request/response from a PHP script that issues a header("Location:"); - a 302 redirect: http://redirector.mysite.com/?unicmd=g+yreka GET /?unicmd=g+yreka HTTP/1.1 Host: redirector.mysite.com User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.9) Gecko/20100330 Fedora/3.5.9-1.fc12 Firefox/3.5.9 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive HTTP/1.1 302 Found Date: Tue, 13 Apr 2010 05:15:43 GMT Server: Apache X-Powered-By: PHP/5.2.11 Location: http://www.google.com/search?q=yreka Content-Type: text/html Vary: User-Agent,Accept-Encoding Content-Encoding: gzip Content-Length: 2108 Keep-Alive: timeout=3, max=100 Connection: Keep-Alive Here's what it looks like when running through the squid proxy (note that "redirector.mysite.com" is not the site running squid or nginx): http://redirector.mysite.com/?unicmd=g+yreka GET /?unicmd=g+yreka HTTP/1.1 Host: redirector.mysite.com User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.9) Gecko/20100330 Fedora/3.5.9-1.fc12 Firefox/3.5.9 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Proxy-Connection: keep-alive If-Modified-Since: Tue, 13 Apr 2010 05:21:02 GMT HTTP/1.0 200 OK Server: nginx/0.7.62 Date: Tue, 13 Apr 2010 05:21:10 GMT Content-Type: text/html Content-Length: 17865 Last-Modified: Tue, 13 Apr 2010 05:21:10 GMT Accept-Ranges: bytes X-Cache: MISS from jefferson X-Cache-Lookup: HIT from jefferson:3128 Via: 1.1 jefferson:3128 (squid/2.7.STABLE6) Connection: keep-alive Proxy-Connection: keep-alive It is basically working - but the URL http://redirector.mysite.com/?unicmd=g+yreka remains unchanged, while displaying the google page (mostly broken as it's using URLs relative to redirector.mysite.com) I've experienced a similar thing with google results pages: when clicking to another page from google, I get a google URL, with the other site's content. Sorry for the long post - many thanks if you've read this far! Any ideas?

  • Azure VM with many IPs or SSL certificates

    - by timmah.faase
    I am looking to move our hosting environment to Azure and by doing so have created a sandpit VM to figure things out. We host around 300-400 websites in IIS and about 2% of these sites have unique, non wildcard certificates all requiring a unique public IP in our current setup. Can you get a range of IPs pointing to 1 VM/Endpoint? Or is it possible to create an SSL proxy? I've never created an SSL proxy but like the idea of it. I'd need advise here on how to proceed if this is the best option. Sorry if this has been answered! Sorry also if my question isn't worded eloquently.

  • Apache + Tomcat error 120006 Using mod_proxy_ajp for Load Balance

    - by Wakaru44
    I have an apache 2 frontend with two nodes, and a backend with two instances of tomcat 6 balance with mod_proxy_ajp. The bbdd is in a separate machine. All machines use RHEL, 6.2 on the frontend, 5.5 on the backend. The infraestructure is virtualized using VMware. # This is the apache config in one of the virtualHost. ProxyPreserveHost On ProxyPass / balancer://liferay/ <Proxy balancer://liferay> BalancerMember ajp://lrab:8009 route=liferaya BalancerMember ajp://lrbb:8009 route=liferayb status=+H ProxySet lbmethod=byrequests nofailover=on </Proxy> The conector in tomcat is now configured like this: <!-- Define an AJP 1.3 Connector on port 8009 --> <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" URIEncoding="UTF-8" enableLookups="false" allowTrace="true" /> Do you think it could be useful to set a maxThreads parameter, like in this post?? in that case, How can i determine a proper number of threads? From time to time, we get errors like this [Tue Sep 18 17:57:02 2012] [error] ajp_read_header: ajp_ilink_receive failed [Tue Sep 18 17:57:02 2012] [error] (120006)APR does not understand this error code: proxy: read response failed from 192.168.1.104:8009 (lrab) And apache switches to the pasive node (if its active) or fails with 503. Some things i have tried so far: I think that i have some performance issues with one of the applications, Here you can see a threadDump But i'm not quite sure about it. I also started to monitor the network connection. I have noticed that there are some pings lost when i have a "ping -f " so maybe it could be a network issue, but the success rate is 100% (so the lost packets are only a few among the flood, but maybe, i don't know, enough to break the link betwen apache and tomcat). I wrote a python script to check connectivity with timestamps on the pings, so i can know when the network fails. After sniffing the network , i can also see some RST packets, but i don't know if that is a normal behaviour (some applications do that to end a network communication). I have also noticed that the applications have problems communicating with the database, but im not even sure if this could be related or not. If you think so, i can post more info about it. I changed the connector on the tomcats to use the native one, but still the same. I need not even a solution to this, but maybe some guidance on how can i troubleshoot this better ¿Analyze threads, monitor mysql performance, sniff the traffic between apaches and tomcats? Ultimately, all i need is to balance the tomcat instances in Active/pasive mode, so if there is another way to do it, i could give it a try.
