Hi.

I have a web application running .NET 2.0.

In the global.asax we have set up a handler for the ApplicationError event.
The handler sends an email with details about the error.
The puzzling thing is that we regularly (5-10 times a week) get this error
message:

System.Web.HttpException: This is an invalid webresource request.
at
System.Web.Handlers.AssemblyResourceLoader.System.Web.IHttpHandler.ProcessRequest(HttpContext
context)
at
System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&
completedSynchronously)

The requested URL for this is http://url:80/WebResource.axd

We don't use web-resources ourselves.

Thanks in advance,
Pete

Hi Peter,

Welcome to MSDN newsgroup.
As for the webresource exception you mentioned, it is likely caused by some
certain client send request to the webresource.axd.... which dosn't contain
the valid querystring parameter.... The WebResource.axd is the new
build-in handler added in ASP.NET 2.0 to help generate resource stream
dynamically from assembly(embeded resource files.....). Some buildin
asp.net resource files (like validation script, webpart script or
style.....) are generated through this handler..... And when use it ,
the url's querystring will contain the encrypted assemblyname + resource
name, thus, if we send such requst without valid paramters , there'll occur
exception....

As for your scenario, not sure whether the request is sent by asp.net
runtime or any other client ... Have you checked the IIS log to see the
source of the request?

Thanks,

Steven Cheng
