HttpHandlers / Modules :: HttpModule That Alters Request.QueryString And Request.Form?

Jan 27, 2011

We're trying to implement functionality that intercepts, inspects, and alters if needed data in the Request.QueryString and Request.Form collections.

Since Request.QueryString and Request.Form are readonly, is it possible to use a HttpModule to do this without Reflection or Response.Redirect?

We're thinking that we can construct a new HttpRequest, and replace the original one. Would there be any implications in doing this?

I know mocking this object is impossible without using HttpRequestWrapper, but wasn't sure whether ASP.NET sets other things beyond the constructor.

HttpHandlers / Modules :: Read Data Sent After A GET Request?

Oct 31, 2010

I'm in a situation where a GET request is made of my server without any content-length header. After the GET request is sent the client then sends a small chunk of data (8 bytes to be exact). It's imperative to note that this data is not meant to be treated as a request body. For this reason asp.net/iis ignores it. I cannot read it and the input stream says it has a length of 0. This is the correct behaviour!

What I need to do is somehow hook into the request processing pipeline early enough to read this data and somehow append it to the request (Items?) I don't know how to do this 'correctly'. I figure I should probably create an IHttpModule to check if the request is of the type that will have this data, then somehow read it.

How would I go about this? How would I be able to read this information in from the stream? I've tried adding an event handler to HttpApplication.BeginRequest but everything I try to read the stream fails. I've read that I could potentially add a custom header using reflection (this would allow me to add a content-length header) but this feels nasty and hacky - I presume there's just a place where I can hook in and handle the reading of the stream before passing it on for further processing.

HttpHandlers / Modules :: Sending Second HttpWebRequest In Sync With First Request

Dec 6, 2010

Using a Windows application I am sending a web request to a web page and getting the response back using the following code

HttpWebRequest oRequest1 = (HttpWebRequest)WebRequest.Create(url);
oRequest1.ContentType = "text/xml";
using (Stream stream = oRequest1.GetRequestStream())
{
stream.Write(fileBytes1, 0, fileBytes2.Length); //fileBytes1 - contains the data of first request
}
HttpWebResponse Response1 = (HttpWebResponse)oRequest1.GetResponse();
->The above code works fine
But I need to enhance the code to accomodate following additional scenario
->Send another request to the same web app and
->get the response back

The first request sent contains the credentials to access the web application the second request sent doesn't have credentials, it must use the credentials of first request. I am using the same (following) code for the second request too. I get an error saying that it's looking for credentials

HttpWebRequest oRequest2 = (HttpWebRequest)WebRequest.Create(url);
oRequest2.ContentType = "text/xml";
using (Stream stream = oRequest2.GetRequestStream())
{
stream.Write(fileBytes2, 0, fileBytes2.Length);
}
HttpWebResponse Response2 = (HttpWebResponse)oRequest2.GetResponse();

So how do I accomplish this? Should I be sending the second request using same session or same connection?

HttpHandlers / Modules :: Adding HTTP Request Header - Operation Not Supported?

Jul 20, 2010

I am trying to call a webservice that requires me to authenticate and then pass the session id returned from the authenticate method to subsequent web service calls. The session id has to be passed as HTTP request header. So I tried using the following code to add the session id to a HTTP request header:

System.Collections.Specialized.NameValueCollection headers =
HttpContext.Current.Request.Headers;
Type t = headers.GetType();
//get the property
System.Reflection.PropertyInfo p = t.GetProperty("IsReadOnly",System.Reflection.BindingFlags.Instance
| System.Reflection.BindingFlags.IgnoreCase | System.Reflection.BindingFlags.NonPublic
| System.Reflection.BindingFlags.FlattenHierarchy);
//unset readonly
p.SetValue(headers, false,
null);
//add a header
headers.Add("Cookie",
"SID=" + sessionId );

The header is supposed to be called "Cookie" and the SID contains the session id. The problem is the last line in the code above gives an exception saying "Operation is not supported on this platform". I am running this code on my dev machine with with Windows XP Professional Service Pack 3 and IIS 5.1. I haven't been able to find any solution to this problem after days of searching. I also tried to deploy my web app on IIS directly but had the same error.

Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)Code is as follows.
