Simply Add in Web.Config file :- Under <system.web> tag

</httpHandlers>

That will solve your problem.

I was having the same problem, but I resolved it. I added compression code to the global.asax within the Application_BeginRequest. I believe the "content-encoding" header was being rewritten after the Application_BeginRequest sub executed, so I kept the compression code in the Application_BeginRequest sub, and moved the Response.AddHeader("Content-Encoding", "gzip") code to the Application_EndRequest sub, and now everything works perfectly.

Samething for me!!! I had to uncheck "Verify that file exists" in the .axd extension properties, found in the web site's Properties (in IIS), and then "Configuration" in the "Home Directory"'s tab.

It now works like a charm!

This is working for me on Windows 2003 server.

I just installed ASP.NET AJAX, it returned error 404 for scriptresource.axd. I went to website properties, Home Directory, Configuration, .axd Extension was missing. Clicked Add, set Executable to c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll, Extension to .axd, Limit to GET,HEAD,POST,DEBUG, checked Script engine, unchecked Verify that file exists.

Now it is working fine and returns javascript code on Scriptresource.axd request.

Thank you for your response. IIS setup is as usual. Nothing special I have made. I havent installed Firebug for FireFox.

But the error is not only in FireFox, In IE it is throwing 'Sys' is undefined error and in ForeFox the data is not loaded but it doesnt throw any error. I have even tried reinstalling AJAX Extension, but it was of no use.

How do you have IIS set up? I know you probably have checked all this, but I am just trying to get a picture of how your setup is.

Do you have the Firebug extension installed for Firefox?

In my appication I am generating the usercontrol dynamically and then I send the generated usercontrol through a webservice to the application. I think there is no difference between dynamically generating a control or sending a static control. In both ways webservice is carrying the html of the control and I am getting the html and just rendering it. In the first retrieval the html is perfectly rendered but when I try to load it several times then I am facing the error. In FireFox I am not facing the error but no html is rendered.

So the controls are dynamically loaded from the webservice? Are the controls dynamically generated from the web service or are the controls static and just receive the data from the we service?

Thanks sir!
