.Net Dojo: Exception Handler
While running one or more ASP.NET websites, it is valuable to have a system where errors encountered by your users are automatically reported so that you can fix them. It is bad practice to let the user’s see the error and it is horribly evil to force them to report the errors themselves. The answer: an automatic exception handler. I developed this handler for use in websites so that any error encountered would be e-mail to a list of developers as well as recorded to the log if desired.
I also give the option of filtering out 404 (Page not found) and 403 (access denied) errors in case you only care about hard exceptions. It the past, I did see one application where we used 404 handling because the structure of the site changed. We implemented an automatic redirection for users who had bookmarks, and we caught 404 errors to find gaps in our redirector.
