HTTP Pipelines: Securely Implement Request Processing, Filtering, and Content Redirection with HTTP


ASP.NET is a flexible and extensible framework for server-side HTTP programming. While most people think of ASP.NET in terms of pages served, there is a lower-level infrastructure sitting beneath this page model. The underlying plumbing is based on a pipeline of app, module, and handler objects. Understanding how this pipeline works is key if you want to get the most out of ASP.NET as an HTTP server platform, while making your process more efficient, and keeping your server secure. This article introduces the architecture of the pipeline and shows how you can use it to add sophisticated functionality to an ASP.NET-based app.

Anonymous Web Site receives "The request failed with HTTP status 401: Unauthorized"


I set up a test website on my local box and was able to access sharepoint search using the querySearch web service from SP.  After I got it all working properly I transferred the code to the target website that is set up with anonymous access for all people on the fab floor.  However from this website I keep getting the 401 error.  It can't be SP because the same code worked from my local website "localhost".  Any suggestions?  we don't want to have to have the fab people log in so we can't not have the box anonymous.  I would appreciate any suggestions very much!!!

HTTP 400 Bad Request Error when uploading to document library


I am running MOSS 3007 Standard on Windows 2003. When trying to upload files larger than about 29Mb, I am getting an HTTP 400 Bad request error. The error states "HTTP Error 400 - Request is badly formed." I am able to successfully upload a 28Mb file. Sharepoint is configured to accept files up to 75Mb.

I have done a fair amount of research on this, but none of the solutions seem to apply to our environment. The two most likely candidates do not apply, for example we are NOT running URLScan (there are a variety of solutions suggesting this could be an issue with uploads of 30Mb or more), and we are on 2003 with IIS6, so again the issue relating to 2008 and IIS7 do not apply.

The "Request is badly formed" part of the request is particularly confusing as most issues I have come across where this error is the symptom point to errors in custom code that is trying to talk to SharePoint. We have done none of our own custom coding and this error is occurring when attempting a simple upload to a document library.

Trying to drag and drop the file across when the document library is open in windows explorer also fails.

I did come across someone saying they had a similar problem which was caused by a damaged content database, however in this case, it is occuring regardless of which content database I use, so either they are all corrupt

page load timeouts and http 500 on MOSS2007


Hi All

I'm hoping someone can point me in the right direction re troubleshooting. We have a MOSS server farm - 3 WFE 1 APP 1 SQL cluster. All Server 2008 sp1 x64. We see occasional http timeouts (HttpException (0x80004005): Request timed out) with associated http 500 error. I have enabled failed request tracing and can see the following:

SiteId 754431215
AppPoolId SharePoint - intranet.*********.com80
ConnId 1610966466
RawConnId 0
RequestURL http://intranet.*********.com:80/Pages/default.aspx
RequestVerb GET

and then later in the trace:

ModuleName IsapiModule
Notification 128
HttpStatus 500
HttpReason Internal Server Error
HttpSubStatus 0
ErrorCode 0
ErrorCode The operation completed successfully. (0x0)

The problem happens on other pages too but the rest of the time the page is returned in less than 5 seconds. The server app logs and sharepoint ULS logs do not give any more detailed info. What I want to know is what other troubleshooting step can I take for http500 errors.

In the past on 32bit environments I have used de

How to bind a WCF Http client to a specific outbound IPAddress before making the request

I want my request to go out through a specific IP Addresses. Is there a way to do that in WCF. The explanation of why I need this is a little long winded so i'd rather not get into that. Here is sample code string ipAddress = ""; IService service; ChannelFactory<IOmlService> factory = new ChannelFactory<IService>(new BasicHttpBinding(), new EndpointAddress("http://" + IPAddress + ":6996/IService")); service = factory.CreateChannel(); service.Test(); Here is an example scenario to explain exactly what i'm looking for. Let's say I have two IPs on my machine ( and Both of them can hit If i run this code now, it will hit the IP (.32) from any of my IPs (.30 or .31). How can i force it to go through a specific IP of mine (say .30). Is there any way to do that using WCF? Thanks

CSS Page Ignored When Printing

This is the first time I have tried using a css page for printing and so far, I am having no success. It appears that the css page is being completely ignored.I am trying to print an asp.net control (datalist or panel - I have tried both). I can get the control to print just fine, but with no css formatting. If I use inline css in the control, it works, but I would rather use a style sheet for this.Any help here would be greatly appreciated.I have two style sheets:<link href="../styles/Styles.css" rel="stylesheet" type="text/css" media="screen" />    <link href="../styles/Print.css" rel="stylesheet" type="text/css" media="print" />I have a master page, a content page and a print page. The control is in the content page and is then printed from the print page:masterpage.mastercontentpage.aspxprint.aspxI have tried attaching the stylesheets in all of the pages (master, content and print) but still the print page ignores the css.What am I doing wrong here?Thanks in advance

WCF webservice: HTTP/1.1 400 Bad Request while sending large input

I am connecting to a WCF based webservice. For certain methods, the input contains a list of objects/structures. When the number of items in this list increases beyond a certain number, the service fails with HTTP/1.1 400 Bad Request when I try to test the same using SOAPUI. I tried changing the web.config file with the following changes: <httpRuntime maxRequestLength="2097151" /> <binding name="basicHTTP" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:01:00" sendTimeout="00:01:00" maxReceivedMessageSize="4194304" maxBufferSize="98547" maxBufferPoolSize="258547"> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> </binding>   Kangkan

The HTTP request is unauthorized with client authentication scheme 'Anonymous'

I am trying to do a soap request from a WebCTRL server. I went to add a service reference, entered the URL to my wsdl and (after prompting me for a username and password) it added the reference and I can create an instance of the service object and makes calls against it.   Dim eval As New WebCTRL_Eval.EvalClient eval.Open() Debug.Print(eval.getValue("#reception_40/lstat"))   I get this back from the server, on open and getvalue.   The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Basic realm="SOAP Access"'.   I understand that it is the HTTP authentication that I need to setup or configure, but just dont understand how to do it.   I have tried eval.ClientCredentials.UserName.UserName = "myusername" eval.ClientCredentials.UserName.Password = "mypassword"   How do I change the client authentication scheme and provide my credentials to it?   Here is what is on my app.config file.   <system.serviceModel>  <bindings>   <wsHttpBinding>    <binding name="EvalSoapBinding"     bypassProxyOnLocal="false"     transactionFlow="false"     hostNameComparisonMode="StrongWildcard"     maxBufferPoolSize="524288"     maxReceivedMessageSize="65536"     messageEncoding="Text"
