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

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

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.

MSMQ and .NET: Send MSMQ Messages Securely Across the Internet with HTTP and SOAP


When creating a distributed system you frequently need to provide for communication between two entities that are not in sync. Microsoft Message Queue Server (MSMQ) provides the kind of store-and-forward messaging in a pre-built infrastructure that can help you address these kinds of messaging needs. In the past, MSMQ was accessed using a COM wrapper. Now there's a .NET wrapper that lets you accomplish your messaging goals easily from your Framework-based code. To illustrate the use of the wrapper, the author builds a messaging application, sends MSMQ messages over the Web, and discusses messaging security.

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

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

While calling Web service gets exception "The request failed with HTTP status 401: Unauthorized"

Hi All, I created a ASP.NET web service, which was hosted on default visual studioserver, and on excecution of webservice it run .exe file which in turn update xml file. Now i hosted this webservice on IIS 6.0 server, and when i run the service, itfails to execute the exe.When i run it on debug mode, i never get any exception.Code...public string HelloWorld()    {        Process myProcess = new Process();        try        {            myProcess.StartInfo.UseShellExecute = false;            // You can start any process,             myProcess.StartInfo.FileName = @"E:\Projects\some.exe";            myProcess.StartInfo.CreateNoWindow = true;            myProcess.Start();            myProcess.Close();            myProcess.Dispose();            return "Suceess";         }&n

POSTing to a remote site and HTTP 302 redirection

hello everyone, Objective: POST data to a remote website and follow the 302 redirect response Synopsis: This works quite well in plain ASP.NET. I can POST to the remote site either using the asp form's action attribute or a button and it's PostBackUrl property. However as soon as I try to accomplish the same behavior inside a Sharepoint page it causes a lot of trouble. Scenario 1 (changing the form's action attribute - less preferred): Imagine this simple publishing aspx page (for what it's worth I encountered the exact same behavior using an application page). <input type="text" name="myField1" value="abc" /> <input type="text" name="myField2" value="abcdef" /> <input type="text" name="myField3" value="123" /> <input type="submit" value="submit now" /> Note that I need to use pure html controls because the remote site expects pre-defined names for these fields. And as we all know control naming is something we cannot really influence up to .NET framework 3.5SP1 (4.0 is supposed to help, right?). Anyway we still need to set the action attribute of the form. This is being done in the page's OnLoad() method. Result: The aspform is being posted to the remote site, the remote site responds with 302 and the browser redirects to the returned ur

Cannot crawl complex URL's without setting a site-wide rule to 'crawl as http content'. Help!

I have pages within a site that use a query string to provide dynamic data to the user (http://<site>/pages/example.aspx?id=1). I can get the content source to index these dynamic pages only if I create a rule which sets the root site (http://<site>/*) to 'include complex urls' and 'crawl sharepoint content as http content'. This is NOT acceptable as changing the crawling protocol from SharePoint's to HTTP will prevent any metadata from being collected on the indexed items. The managed metadata feature is a critical component to our SharePoint applications. To dispel any wondering of whether or not this is simply a configuration error on my part refer to http://social.technet.microsoft.com/Forums/en-US/sharepointsearch/thread/4ff26b26-84ab-4f5f-a14a-48ab7ec121d5 . The issue mentioned is my exact problem but the solution is unusable as I mentioned before. Keep in mind this is for an external publishing site and my search scope is being trimmed using content classes to only include documents/pages (STS_List_850 and STS_ListItem_DocumentLibrary). Creating a new web site content source and adding it to my scope presents 2 problems: duplicate content in scope and no content class defining it that I know of. What options do I have?

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.

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"

WCF The request failed with HTTP status 404: Not Found



I get the error above with a WCF service I've deployed to a Windows Server 2008 box (with IIS 7). When using a test client with a proxy WSDL class to try to consume the service this error pops up while debugging. Using http is fine, however using https causes the error. We do have an SSL on the URL for the WCF service.

Is there a setting I'm missing?
