Is there any means to track where within code a 404 error is handled? We have a site that we have taken over that doesn't seem to be reacting as expected. We have changed the IIS custom errors page to point to the new page we would like but something seems to still be redirecting it to the old 404.htm file in the root of this site. We have not been able to track down where or why this happens. Any suggestions on how we might find the referring logic?
