How to get which page threw an exception to Application_error in aspx

Question

I have a general exception handler, Application_error in my global.asx what I'm trying to isolate all the uncaught exceptions on all my many pages. I don't want to use Page_error to catch exception because it's inefficient to call that on so many pages. So where in the exception can I find what page actually caused the exception.

anything would be apprecaited.

Answer 1

HttpContext con = HttpContext.Current;
con.Request.Url.ToString()

Answer 2

Remember, the page is not (should not) always be the cause of the exception. It could just as easily be coming from another assembly - and if you don't have your logic in your codebehinds, it likely will be coming from another assembly. Don't get me wrong, it is great to know which page, from the aspect of saying X Page caused Y exception in Z assembly.
