Change the requested URL to WebResource.axd

Question

My web application (http://www.something.com/social/competition/) is currently requesting the WebResource.axd file as follows:

<script src="/WebResource.axd?d=xxx" type="text/javascript"></script> 

Since we use urlrewiting in Netscaler to forward all requests for the / social folder to a separate server farm containing this application, the root path "/" will not be correctly resolved because it will request a resource from the something.com application.

Therefore, I need to change the url of the requested script so that it explicitly requests it:

 <script src="/social/WebResource.axd?d=xxx" type="text/javascript"></script> 

or query it using a relative path:

 <script src="WebResource.axd?d=xxx" type="text/javascript"></script> 

So far, I have been looking at overriding the rendering method using the control adapter and other other things, but have not received anything yet. Help me please.

That's right, so after extensive research it turns out that it is almost impossible to override the rendering process for these files. So the only other option was a dirty, dirty, terrible hack!

 protected void Page_Load(object sender, EventArgs e) { //Initialises my dirty hack to remove the leading slash from all web reference files. Response.Filter = new WebResourceResponseFilter(Response.Filter); } public class WebResourceResponseFilter : Stream { private Stream baseStream; public WebResourceResponseFilter(Stream responseStream) { if (responseStream == null) throw new ArgumentNullException("ResponseStream"); baseStream = responseStream; } public override bool CanRead { get { return baseStream.CanRead; } } public override bool CanSeek { get { return baseStream.CanSeek; } } public override bool CanWrite { get { return baseStream.CanWrite; } } public override void Flush() { baseStream.Flush(); } public override long Length { get { return baseStream.Length; } } public override long Position { get { return baseStream.Position; } set { baseStream.Position = value; } } public override int Read(byte[] buffer, int offset, int count) { return baseStream.Read(buffer, offset, count); } public override long Seek(long offset, System.IO.SeekOrigin origin) { return baseStream.Seek(offset, origin); } public override void SetLength(long value) { baseStream.SetLength(value); } public override void Write(byte[] buffer, int offset, int count) { //Get text from response stream. string originalText = System.Text.Encoding.UTF8.GetString(buffer, offset, count); //Alter the text. originalText = originalText.Replace("/WebResource.axd", "WebResource.axd"); //Write the altered text to the response stream. buffer = System.Text.Encoding.UTF8.GetBytes(originalText); this.baseStream.Write(buffer, 0, buffer.Length); } 

This hooks the stream to the page and replaces all occurrences of "/WebResource.axd" with "WebResource.axd". Since this is a relative path, it decides perfectly!

I needed another solution that required installing the web application in a virtual directory that simulated the redirection of the / social keyword. This will cause asp.net to update HttpRuntime.AppDomainAppVirtualPath to include "/ social" in the links on the page and therefore fix it properly.

Big shout, scream!
