  • Squid, authentication, Outlook Anywhere, Windows 7 and HTTP 1.1 = NIGHTMARE

    - by Massimo
    I'm running a Squid proxy (latest version, 3.1.4) on Linux CentOS 5.4 with Samba 3.5.4, in order to allow authenticated web access for domain users; everything works fine, and even Windows 7 clients are fully supported. Authentication is transparent for domain users, while it is explicitly requested for non-domain ones, and it works if the user can provide valid domain credentials. All nice and good. Then, Outlook Anywhere kicks in and pain and suffering ensue. When Outlook (be it 2007 or 2010, it doesn't matter) runs on Windows XP clients, it connects gracefully through the Squid proxy to its remote Exchange server. When it runs on Windows 7, it doesn't. If the authentication requirement is lifted from the proxy, everything works on Windows 7 too, so the problem is obviously related to NTLM authentication with Squid. Digging more deeply (WireShark), I discovered Outlook Anywhere uses HTTP 1.1 when it runs on Windows 7, while it uses HTTP 1.0 when on Windows XP. And it looks like Squid, even in its latest incarnation, still has some serious troubles handling HTTP 1.1 properly, particularly when SSL and proxy authentication are thrown in the mix. While waiting for Squid to fully and officially support HTTP 1.1 (and it looks like this could take quite a long time), I'm looking for one of the following solutions: Make Squid handle this correctly, if it is at all possible. Identify Outlook Anywhere connections and have Squid not require authentication for them. But it isn't easy: again, the behaviour of Outlook differs when running on Windows XP and Windows 7, and while on Windows XP Outlook sends a really nice user-agent string of "MSRPC", on Windows 7 it doesn't send any (why? WHY?!?). Force Outlook Anywhere to use HTTP 1.0 even when running on Windows 7. And no, this is not as simple as deselecting "use HTTP 1.1" in Internet Explorer, looks like Outlook ignores that setting and chooses on its own which protocol to use. Any other feasible solution which doesn't involve whitelisting specific destination Exchange servers, which is the last-resort solution I'm trying to avoid.

  • http server implentation, the page does not show properly

    - by none
    well, as i am doing a small project of coding an http server. the code is at http://code.google.com/p/reactor/ the current puzzle is when asked to parse a page with java script and css. As an http server it just sends a page (copied from another website) and it parsed inproperly. when a simple html page is been parse , by my firefox, it shows ok, however when parsing a more complex page(css+javascript) the page is all wired like this : ???? ?????

  • Force gdm login screen to the primary monitor

    - by Kirill
    I have two monitors attached to my video card. Primary monitor has a resolution equal to 1280x1024 and the second has 1920x1200. My gdm login screen always appears on the second monitor even if it is switched off. My question is how to force gdm to show the login screen always on the primary monitor with resolution 1280x1024? I use Nvidia GT9500 videcard in Twinview mode. I can't use Xinerama because vpdau doesn't work correclty in this mode. What I have found is that mouse pointer always appears in the center of union of the screens and center is always on the monitor with higher resolution. Login screen always shows where mouse cursor is. Now my primary monitor has a resolution equal to 1920x1080. The problem still persists, mouse cursor always appears in the right-bottom corner of the second monitor.

  • Is HTTP 404 appropriate for out of range page number on paged content?

    - by WooYek
    I have a site that is mainly showing a paged list of content (articles, data element's, etc.), and I'm wondering about returning HTTP 404 when user navigates outside of the available list range. Some sites just display "No results/Page number out of range" and some return additionally return HTTP 404 status. What's your take on that, and why? UPDATE It's not and api response. This question is in regard to user viewed pages that among other things show a list/table in the main area.

  • Real time embeddable http server library required

    - by Howard May
    Having looked at several available http server libraries I have not yet found what I am looking for and am sure I can't be the first to have this set of requirements. I need a library which presents an API which is 'pipelined'. Pipelining is used to describe an HTTP feature where multiple HTTP requests can be sent across a TCP link at a time without waiting for a response. I want a similar feature on the library API where my application can receive all of those request without having to send a response (I will respond but want the ability to process multiple requests at a time to reduce the impact of internal latency). So the web server library will need to support the following flow 1) HTTP Client transmits http request 1 2) HTTP Client transmits http request 2 ... 3) Web Server Library receives request 1 and passes it to My Web Server App 4) My Web Server App receives request 1 and dispatches it to My System 5) Web Server receives request 2 and passes it to My Web Server App 6) My Web Server App receives request 2 and dispatches it to My System 7) My Web Server App receives response to request 1 from My System and passes it to Web Server 8) Web Server transmits HTTP response 1 to HTTP Client 9) My Web Server App receives response to request 2 from My System and passes it to Web Server 10) Web Server transmits HTTP response 2 to HTTP Client Hopefully this illustrates my requirement. There are two key points to recognise. Responses to the Web Server Library are asynchronous and there may be several HTTP requests passed to My Web Server App with responses outstanding. Additional requirements are Embeddable into an existing 'C' application Small footprint; I don't need all the functionality available in Apache etc. Efficient; will need to support thousands of requests a second Allows asynchronous responses to requests; their is a small latency to responses and given the required request throughput a synchronous architecture is not going to work for me. Support persistent TCP connections Support use with Server-Push Comet connections Open Source / GPL support for HTTPS Portable across linux, windows; preferably more. I will be very grateful for any recommendation Best Regards

  • How can I extend the desktop onto an external monitor/projector?

    - by hellocatfood
    I've plugged in a projector into my laptop and I'm attempting to extend the desktop onto it (so that I can run a full screen app on the projector and have the controls on my laptop). I'm able to mirror the screens effectively (it does this by default) but I can't extend it. When I untick "Mirror screens" and press apply it asks me to log out and then back in again but it goes back to mirroring the screens. I'm able to extend desktop on to my external monitor at home, just not this projector. Is there a manual way or other way to do this other that through Monitors setting? My computer model is Dell Studio 1555: Pentium Dual Core T4300(2.1GHz,800MHz,1MB), 4096MB 800MHz DDR2 Dual Channel, 512 MB ATI Mobility RADEON HD 4570 using the ATI proprietary driver. My screen resolution is 1366x768 (16:9) The projector that it wont connect properly is a Hitachi CPX3. That page specifies that it's especially designed for projectors that use 16:10 aspect ratio, but considering my external monitor at home uses 4:3 should the differences in aspect ratio matter or be causing this error?

  • SQL Monitor’s data repository: Alerts

    - by Chris Lambrou
    In my previous post, I introduced the SQL Monitor data repository, and described how the monitored objects are stored in a hierarchy in the data schema, in a series of tables with a _Keys suffix. In this post I had planned to describe how the actual data for the monitored objects is stored in corresponding tables with _StableSamples and _UnstableSamples suffixes. However, I’m going to postpone that until my next post, as I’ve had a request from a SQL Monitor user to explain how alerts are stored. In the SQL Monitor data repository, alerts are stored in tables belonging to the alert schema, which contains the following five tables: alert.Alert alert.Alert_Cleared alert.Alert_Comment alert.Alert_Severity alert.Alert_Type In this post, I’m only going to cover the alert.Alert and alert.Alert_Type tables. I may cover the other three tables in a later post. The most important table in this schema is alert.Alert, as each row in this table corresponds to a single alert. So let’s have a look at it. SELECT TOP 100 AlertId, AlertType, TargetObject, [Read], SubType FROM alert.Alert ORDER BY AlertId DESC;  AlertIdAlertTypeTargetObjectReadSubType 165550397:Cluster,1,4:Name,s29:srp-mr03.testnet.red-gate.com,9:SqlServer,1,4:Name,s0:,10 265549387:Cluster,1,4:Name,s29:srp-mr03.testnet.red-gate.com,7:Machine,1,4:Name,s0:,10 365548187:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s15:FavouriteThings,00 465547157:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s15:FavouriteThings,00 565546147:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s15:FavouriteThings,00 665545187:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s14:SqlMonitorData,00 765544157:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s14:SqlMonitorData,00 865543147:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s14:SqlMonitorData,00 965542187:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s4:msdb,00 1065541147:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s4:msdb,00 11…     So what are we seeing here, then? Well, AlertId is an auto-incrementing identity column, so ORDER BY AlertId DESC ensures that we see the most recent alerts first. AlertType indicates the type of each alert, such as Job failed (6), Backup overdue (14) or Long-running query (12). The TargetObject column indicates which monitored object the alert is associated with. The Read column acts as a flag to indicate whether or not the alert has been read. And finally the SubType column is used in the case of a Custom metric (40) alert, to indicate which custom metric the alert pertains to. Okay, now lets look at some of those columns in more detail. The AlertType column is an easy one to start with, and it brings use nicely to the next table, data.Alert_Type. Let’s have a look at what’s in this table: SELECT AlertType, Event, Monitoring, Name, Description FROM alert.Alert_Type ORDER BY AlertType;  AlertTypeEventMonitoringNameDescription 1100Processor utilizationProcessor utilization (CPU) on a host machine stays above a threshold percentage for longer than a specified duration 2210SQL Server error log entryAn error is written to the SQL Server error log with a severity level above a specified value. 3310Cluster failoverThe active cluster node fails, causing the SQL Server instance to switch nodes. 4410DeadlockSQL deadlock occurs. 5500Processor under-utilizationProcessor utilization (CPU) on a host machine remains below a threshold percentage for longer than a specified duration 6610Job failedA job does not complete successfully (the job returns an error code). 7700Machine unreachableHost machine (Windows server) cannot be contacted on the network. 8800SQL Server instance unreachableThe SQL Server instance is not running or cannot be contacted on the network. 9900Disk spaceDisk space used on a logical disk drive is above a defined threshold for longer than a specified duration. 101000Physical memoryPhysical memory (RAM) used on the host machine stays above a threshold percentage for longer than a specified duration. 111100Blocked processSQL process is blocked for longer than a specified duration. 121200Long-running queryA SQL query runs for longer than a specified duration. 131400Backup overdueNo full backup exists, or the last full backup is older than a specified time. 141500Log backup overdueNo log backup exists, or the last log backup is older than a specified time. 151600Database unavailableDatabase changes from Online to any other state. 161700Page verificationTorn Page Detection or Page Checksum is not enabled for a database. 171800Integrity check overdueNo entry for an integrity check (DBCC DBINFO returns no date for dbi_dbccLastKnownGood field), or the last check is older than a specified time. 181900Fragmented indexesFragmentation level of one or more indexes is above a threshold percentage. 192400Job duration unusualThe duration of a SQL job duration deviates from its baseline duration by more than a threshold percentage. 202501Clock skewSystem clock time on the Base Monitor computer differs from the system clock time on a monitored SQL Server host machine by a specified number of seconds. 212700SQL Server Agent Service statusThe SQL Server Agent Service status matches the status specified. 222800SQL Server Reporting Service statusThe SQL Server Reporting Service status matches the status specified. 232900SQL Server Full Text Search Service statusThe SQL Server Full Text Search Service status matches the status specified. 243000SQL Server Analysis Service statusThe SQL Server Analysis Service status matches the status specified. 253100SQL Server Integration Service statusThe SQL Server Integration Service status matches the status specified. 263300SQL Server Browser Service statusThe SQL Server Browser Service status matches the status specified. 273400SQL Server VSS Writer Service statusThe SQL Server VSS Writer status matches the status specified. 283501Deadlock trace flag disabledThe monitored SQL Server’s trace flag cannot be enabled. 293600Monitoring stopped (host machine credentials)SQL Monitor cannot contact the host machine because authentication failed. 303700Monitoring stopped (SQL Server credentials)SQL Monitor cannot contact the SQL Server instance because authentication failed. 313800Monitoring error (host machine data collection)SQL Monitor cannot collect data from the host machine. 323900Monitoring error (SQL Server data collection)SQL Monitor cannot collect data from the SQL Server instance. 334000Custom metricThe custom metric value has passed an alert threshold. 344100Custom metric collection errorSQL Monitor cannot collect custom metric data from the target object. Basically, alert.Alert_Type is just a big reference table containing information about the 34 different alert types supported by SQL Monitor (note that the largest id is 41, not 34 – some alert types have been retired since SQL Monitor was first developed). The Name and Description columns are self evident, and I’m going to skip over the Event and Monitoring columns as they’re not very interesting. The AlertId column is the primary key, and is referenced by AlertId in the alert.Alert table. As such, we can rewrite our earlier query to join these two tables, in order to provide a more readable view of the alerts: SELECT TOP 100 AlertId, Name, TargetObject, [Read], SubType FROM alert.Alert a JOIN alert.Alert_Type at ON a.AlertType = at.AlertType ORDER BY AlertId DESC;  AlertIdNameTargetObjectReadSubType 165550Monitoring error (SQL Server data collection)7:Cluster,1,4:Name,s29:srp-mr03.testnet.red-gate.com,9:SqlServer,1,4:Name,s0:,00 265549Monitoring error (host machine data collection)7:Cluster,1,4:Name,s29:srp-mr03.testnet.red-gate.com,7:Machine,1,4:Name,s0:,00 365548Integrity check overdue7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s15:FavouriteThings,00 465547Log backup overdue7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s15:FavouriteThings,00 565546Backup overdue7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s15:FavouriteThings,00 665545Integrity check overdue7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s14:SqlMonitorData,00 765544Log backup overdue7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s14:SqlMonitorData,00 865543Backup overdue7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s14:SqlMonitorData,00 965542Integrity check overdue7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s4:msdb,00 1065541Backup overdue7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s4:msdb,00 Okay, the next column to discuss in the alert.Alert table is TargetObject. Oh boy, this one’s a bit tricky! The TargetObject of an alert is a serialized string representation of the position in the monitored object hierarchy of the object to which the alert pertains. The serialization format is somewhat convenient for parsing in the C# source code of SQL Monitor, and has some helpful characteristics, but it’s probably very awkward to manipulate in T-SQL. I could document the serialization format here, but it would be very dry reading, so perhaps it’s best to consider an example from the table above. Have a look at the alert with an AlertID of 65543. It’s a Backup overdue alert for the SqlMonitorData database running on the default instance of granger, my laptop. Each different alert type is associated with a specific type of monitored object in the object hierarchy (I described the hierarchy in my previous post). The Backup overdue alert is associated with databases, whose position in the object hierarchy is root → Cluster → SqlServer → Database. The TargetObject value identifies the target object by specifying the key properties at each level in the hierarchy, thus: Cluster: Name = "granger" SqlServer: Name = "" (an empty string, denoting the default instance) Database: Name = "SqlMonitorData" Well, look at the actual TargetObject value for this alert: "7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s14:SqlMonitorData,". It is indeed composed of three parts, one for each level in the hierarchy: Cluster: "7:Cluster,1,4:Name,s7:granger," SqlServer: "9:SqlServer,1,4:Name,s0:," Database: "8:Database,1,4:Name,s14:SqlMonitorData," Each part is handled in exactly the same way, so let’s concentrate on the first part, "7:Cluster,1,4:Name,s7:granger,". It comprises the following: "7:Cluster," – This identifies the level in the hierarchy. "1," – This indicates how many different key properties there are to uniquely identify a cluster (we saw in my last post that each cluster is identified by a single property, its Name). "4:Name,s14:SqlMonitorData," – This represents the Name property, and its corresponding value, SqlMonitorData. It’s split up like this: "4:Name," – Indicates the name of the key property. "s" – Indicates the type of the key property, in this case, it’s a string. "14:SqlMonitorData," – Indicates the value of the property. At this point, you might be wondering about the format of some of these strings. Why is the string "Cluster" stored as "7:Cluster,"? Well an encoding scheme is used, which consists of the following: "7" – This is the length of the string "Cluster" ":" – This is a delimiter between the length of the string and the actual string’s contents. "Cluster" – This is the string itself. 7 characters. "," – This is a final terminating character that indicates the end of the encoded string. You can see that "4:Name,", "8:Database," and "14:SqlMonitorData," also conform to the same encoding scheme. In the example above, the "s" character is used to indicate that the value of the Name property is a string. If you explore the TargetObject property of alerts in your own SQL Monitor data repository, you might find other characters used for other non-string key property values. The different value types you might possibly encounter are as follows: "I" – Denotes a bigint value. For example, "I65432,". "g" – Denotes a GUID value. For example, "g32116732-63ae-4ab5-bd34-7dfdfb084c18,". "d" – Denotes a datetime value. For example, "d634815384796832438,". The value is stored as a bigint, rather than a native SQL datetime value. I’ll describe how datetime values are handled in the SQL Monitor data repostory in a future post. I suggest you have a look at the alerts in your own SQL Monitor data repository for further examples, so you can see how the TargetObject values are composed for each of the different types of alert. Let me give one further example, though, that represents a Custom metric alert, as this will help in describing the final column of interest in the alert.Alert table, SubType. Let me show you the alert I’m interested in: SELECT AlertId, a.AlertType, Name, TargetObject, [Read], SubType FROM alert.Alert a JOIN alert.Alert_Type at ON a.AlertType = at.AlertType WHERE AlertId = 65769;  AlertIdAlertTypeNameTargetObjectReadSubType 16576940Custom metric7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s6:master,12:CustomMetric,1,8:MetricId,I2,02 An AlertType value of 40 corresponds to the Custom metric alert type. The Name taken from the alert.Alert_Type table is simply Custom metric, but this doesn’t tell us anything about the specific custom metric that this alert pertains to. That’s where the SubType value comes in. For custom metric alerts, this provides us with the Id of the specific custom alert definition that can be found in the settings.CustomAlertDefinitions table. I don’t really want to delve into custom alert definitions yet (maybe in a later post), but an extra join in the previous query shows us that this alert pertains to the CPU pressure (avg runnable task count) custom metric alert. SELECT AlertId, a.AlertType, at.Name, cad.Name AS CustomAlertName, TargetObject, [Read], SubType FROM alert.Alert a JOIN alert.Alert_Type at ON a.AlertType = at.AlertType JOIN settings.CustomAlertDefinitions cad ON a.SubType = cad.Id WHERE AlertId = 65769;  AlertIdAlertTypeNameCustomAlertNameTargetObjectReadSubType 16576940Custom metricCPU pressure (avg runnable task count)7:Cluster,1,4:Name,s7:granger,9:SqlServer,1,4:Name,s0:,8:Database,1,4:Name,s6:master,12:CustomMetric,1,8:MetricId,I2,02 The TargetObject value in this case breaks down like this: "7:Cluster,1,4:Name,s7:granger," – Cluster named "granger". "9:SqlServer,1,4:Name,s0:," – SqlServer named "" (the default instance). "8:Database,1,4:Name,s6:master," – Database named "master". "12:CustomMetric,1,8:MetricId,I2," – Custom metric with an Id of 2. Note that the hierarchy for a custom metric is slightly different compared to the earlier Backup overdue alert. It’s root → Cluster → SqlServer → Database → CustomMetric. Also notice that, unlike Cluster, SqlServer and Database, the key property for CustomMetric is called MetricId (not Name), and the value is a bigint (not a string). Finally, delving into the custom metric tables is beyond the scope of this post, but for the sake of avoiding any future confusion, I’d like to point out that whilst the SubType references a custom alert definition, the MetricID value embedded in the TargetObject value references a custom metric definition. Although in this case both the custom metric definition and custom alert definition share the same Id value of 2, this is not generally the case. Okay, that’s enough for now, not least because as I’m typing this, it’s almost 2am, I have to go to work tomorrow, and my alarm is set for 6am – eek! In my next post, I’ll either cover the remaining three tables in the alert schema, or I’ll delve into the way SQL Monitor stores its monitoring data, as I’d originally planned to cover in this post.

  • HTTP response time profiling

    - by Sparsh Gupta
    Hello I have a nginx reverse proxy. The server is close to serving 600-700 requests per second. I have a Munin HTTP load time plugin which is outputting this: http://monitor.wingify.com/munin/visualwebsiteoptimizer.com/lb1.visualwebsiteoptimizer.com-http_loadtime.html Now, the problem is I am seeing some spikes in the graph. Expected response times should always be under 200ms. I am keeping an eye on syslog and messages but I am unable to figure out the actual cause of this. I was wondering if there is any good HTTP response time profiling system which I can install / embed with this nginx server and get a detailed reports / logs on the breakup of time taken by different things and what exactly is the cause of the spikes. The profiling system would also help me understand bottlenecks and how can I further optimize the latency. Most important right now is to investigate the cause of the spikes in the HTTP load time graphs (similar pattern is reported by external monitors - Pingdom) and to fix it to get consistent response times Thanks

    Hi I would like to have a http POST request method CAPTURE filter I know it is easy to do it by display filter http.request.method==POST but I need tcpdump compatible I wrote tcp dst port 80 and (tcp[13] = 0x18) But it is not perfect... tcp dst port 80 and (tcp[((tcp[12:1] & 0xf0) 2):4] = 0x504f5354) works better, but... packages are not treated as a http packages, so I can not do my further display filters... and is there any way to not display frame, tcp, ip and http header information, only data-text-lines field value (content of POST)? or same thing in tcpdump, only dumping of POSTed html form content?

  • HTTP Headers - need to check OPTIONS

    - by chris
    I've received the results of a pen test and there is some unwanted exposure in the HTTP OPTIONS where the fact that Frontpage Server Extensions was available (now removed) was reported. I need to run a check on the OPTIONS to see whether it has been removed. The test output from the report is below, I need to recreate it to establish that it has gone but don't know how to check the OPTIONS, I can only find tools that seem to check the "HEAD / HTTP/1.1". Does anyone know how to test this - I'm running a Windows environment?

  • Apache, Tomcat 5 and problem with HTTP basic auth

    - by Juha Syrjälä
    I have setup a Tomcat with a webapp that uses http basic auth in some of its URLs. There is a Apache server in front of the Tomcat. I have setup Apache as a proxy like this (all traffic should go directly to tomcat): /etc/httpd/conf.d/proxy_ajp.conf: LoadModule proxy_ajp_module modules/mod_proxy_ajp.so ProxyPass / ajp://localhost:8009/ ProxyPassReverse / ajp://localhost:8009/ There is a webapp installed to root of Tomcat (ROOT.war), so I should be able to use http://localhost/ to access my webapp. But it is not working with http basic auth. The problem is that everything works until I try to access URL that are protected by the HTTP basic auth. URLs without authentication work just fine. When accessing this url via apache I am getting an error message from Apache. If I access the same URL directly from tomcat, everything works just fine. I am getting this to Apache error log: [Wed Sep 01 21:34:01 2010] [error] proxy: dialog to [::1]:8009 (localhost) failed access log looks like this: ::1 - - [01/Sep/2010:21:34:01 +0300] "GET /protected_path/ HTTP/1.0" 503 360 "-" "w3m/0.5.2" I am using: Fedora release 13 (Goddard) httpd-2.2.16-1.fc13.x86_64 tomcat5-5.5.27-7.4.fc12.noarch The basic auth is implemented in the webapp (not in Apache or Tomcat). The webapp is actually implemented in Scala/Lift, but that shouldn't matter. The auth works if I access the tomcat directly. Error message that I am getting from Apache. It is curious that the title is Unauthorized and not Internal error: Unauthorized The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later. Apache/2.2.16 (Fedora) Server at my.server.name.com Port 80 It could be that Apache is seeing a some thing else than 200 OK response and thinks that it is an error when it actually should pass the received 401 Unauthorized response directly to browser. If this is the problem, how to fix it?

  • HTTP-DAV on IIS 7.0

    - by Ismail
    I wan't to integrate .NET Application Updater Component in my application for auto update of client application. It says The .NET Application Updater component uses HTTP-DAV to download the application update and thus requires a Web server that supports HTTP-DAV. IIS 5.0 that comes with Windows 2000 and newer operating systems support HTTP-DAV. My server is a Windows 2008 Server and runs IIS 7.0. Does IIS 7.0 support "HTTP-DAV"? And if yes how can I enable it?

  • Incorrect gzipping of http requests, can't find who's doing it

    - by Ned Batchelder
    We're seeing some very strange mangling of HTTP responses, and we can't figure out what is doing it. We have an app server handling JSON requests. Occasionally, the response is returned gzipped, but with incorrect headers that prevent the browser from interpreting it correctly. The problem is intermittent, and changes behavior over time. Yesterday morning it seemed to fail 50% of the time, and in fact, seemed tied to one of our two load-balanced servers. Later in the afternoon, it was failing only 20 times out of 1000, and didn't correlate with an app server. The two app servers are running Apache 2.2 with mod_wsgi and a Django app stack. They have identical Apache configs and source trees, and even identical packages installed on Red Hat. There's a hardware load balancer in front, I don't know the make or model. Akamai is also part of the food chain, though we removed Akamai and still had the problem. Here's a good request and response: * Connected to example.com (97.7.79.129) port 80 (#0) > POST /claim/ HTTP/1.1 > User-Agent: curl/7.19.7 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15 > Host: example.com > Accept: */* > Referer: http://example.com/apps/ > Accept-Encoding: gzip,deflate > Content-Length: 29 > Content-Type: application/x-www-form-urlencoded > } [data not shown] < HTTP/1.1 200 OK < Server: Apache/2 < Content-Language: en-us < Content-Encoding: identity < Content-Length: 47 < Content-Type: application/x-javascript < Connection: keep-alive < Vary: Accept-Encoding < { [data not shown] * Connection #0 to host example.com left intact * Closing connection #0 {"msg": "", "status": "OK", "printer_name": ""} And here's a bad one: * Connected to example.com (97.7.79.129) port 80 (#0) > POST /claim/ HTTP/1.1 > User-Agent: curl/7.19.7 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15 > Host: example.com > Accept: */* > Referer: http://example.com/apps/ > Accept-Encoding: gzip,deflate > Content-Length: 29 > Content-Type: application/x-www-form-urlencoded > } [data not shown] < HTTP/1.1 200 OK < Server: Apache/2 < Content-Language: en-us < Content-Encoding: identity < Content-Type: application/x-javascript < Content-Encoding: gzip < Content-Length: 59 < Connection: keep-alive < Vary: Accept-Encoding < X-N: S < { [data not shown] * Connection #0 to host example.com left intact * Closing connection #0 ?V?-NW?RPR?QP*.I,)-???A??????????T??Z? ??/ There are two things to notice about the bad response: It has two Content-Encoding headers, and the browsers seem to use the first. So they see an identity encoding header, and gzipped content, so they can't interpret the response. The bad response has an extra "X-N: S" header. Perhaps if I could find out what intermediary adds "X-N: S" headers to responses, I could track down the culprit...

  • Strange request - http://66.196.81.202/error/vote

    - by mplungjan
    Hi a friend of mine is asking about the request which can for example be found here: http://www.geoidee.ch/geodata/geoserver-2.0.0/logs/2010_11_23.request.log His original message: On a couple of hundred web sites worldwide, one of the 50 most popular "File not found" error 404 is caused by the following request: "GET http://66.196.81.202/error/vote HTTP/1.0" It originates from a user agent that purports to be an iPhone. The two requests that hit my servers appeared to originate near Frankfort, Germany. The IP address in the request is part of Yahoo although I doubt that Yahoo had any intentional part. fe1.buzz.vip.re1.yahoo.com The HTTP request has a host header 66.196.81.202 and a X-Forwarded-For of 96.6.99.16 and my IP address I expected to be able to do a Google search and find some kind of security bulletin on it, but I found nothing. It could just be that my search skills are deficient. Thanks for any pointers to what this could be

  • http(/* argument here */) How is this Object (Http) being used without an explicit or implicit meth

    - by Randin
    In the example for coding with Json using Databinder Dispatch Nathan uses an Object (Http) without a method, shown here: import dispatch._ import Http._ Http("http://www.fox.com/dollhouse/" >>> System.out ) How is he doing this? Thank you for all of the answers unfortunatly I was not specific enough... It looks like it is simply passing an argument to a constructor of class or companion object Http. In another example, I've seen another form: http = new Http http(/* argument here */) Is this valid Scala? I guess it must be, because the author is a Scala expert. But it makes no sense to me. Actions are usually performed by invoking methods on objects, whether explicitly as object.doSomething() or implicitly as object = something (using the apply() method underneath the syntactic sugar). All I can think of is that a constructor is being used to do something in addition to constructing an object. In other words, it is having side effects, such as in this case going off and doing something on the web.

  • Eclipse 3.5.1 update error (HTTP 503)

    - by PiedPiper
    I'm trying to update Eclipse 5.3.1 (on Gentoo Linux) from the Galileo Discovery Site and I get this error message: Network connection problems encountered during search. Unable to access "http://download.eclipse.org/releases/galileo". Error accessing site stream. [Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd] Server returned HTTP response code: 503 for URL: http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd Error accessing site stream.

But how do I persuade Eclipse to stop requesting it?

  • Mercurial mirror: abort: No such file or directory: http://[...]/00manifest.i

    - by Sridhar Ratnakumar
    I am trying to setup a daily mirror of a mercurial repository - code.python.org in particular - within our local network, and serve that via Apache HTTPD. On the remote host that hosts apache, I did this: $ cd /var/www $ hg clone http://code.python.org/hg/trunk/ On my macbook, I ran: $ hg -v clone http://remote/trunk/ (falling back to static-http) abort: No such file or directory: http://remote/trunk/.hg/store/00manifest.i Google does not show any relevant result for this particular error. I remember back in those days being able to setup Bazaar mirrors by a simple clone. Doesn't Mercurial work like that? How do I setup a mirror that must further act like a clone URL?

  • ftp server offering http access ?

    - by MikeJ
    Is there an FTP server that can also provide access via HTTP? Or what do I need to do to set up the mirror of FTP through HTTP access ? Some of my clients cannot access our FTP because of corporate policy and cannot get updates from me. However, they can use HTTP. Currently I use filezilla because it was fast/easy to set up but would switch to something with more flexibility.
