I have not tried your approach yet but from reading it seems logical and should work. Even if it does not work, I thank you very much for taking the time to work with me on this problem. I am making baby steps in learning ASP.NET so I am slow <g>.

>>I do want to have my own custom 404 error page. But my point is that with the global error code in Application_Error, it is not possible. If user enters wrong URL, the error code in Application_Error has to handle it. It would be nice if the exception handling code in Application_Error could redirect error to the custom 404 page. But the error handling code in Application_Error does not knows that the error is caused by wrong URL or anything else.
