How to know which resource is throwing a HttpException in my Application_Error

The Application_Error event is being raised in my application with a HttpException. Inside the exception I see a 404 error code - resource not found.

I've already used Firebug to check if there's some image/css/js with 404 开发者_高级运维error code and didn't found.

The question is: How can I get the resource that's firing this error?

Thanks,

Armando

Try checking Request.Url in Application_Error in Global.asax.
