>I don't think you do. Your code doesn't catch that "exception". Your code isn't even running. The web server (IIS) catches it and "handles" it by displaying the 404 error page (C:\WINNT\help\iisHelp\common\404b.htm on my machine). You can change this page to display your own friendly page that brings up and index of your site, for example.

What happened when I tried it yesterday, the exception handling in Application_Error catches the error when user enters wrong URL. Therefore, the page 404b.htm never gets displayed. And I don't know how to make Application_Error ignore some errors.
