I currently have a IHTTPModule set up to handle all 404 and 500 errors. It is working on aspx pages, and items set up on those pages, but not on any other extensions. I have changed IIS to use aspnet_asapi.dll as the wildcard. Is there any way to route all traffic, even image and plain text, through the .net handlers so that 404's and 500 errors will be displayed and send error emails correctly?
