Pre written Exception Handler for ASP.Net

I'm looking for a Exception Handler for asp.net that does email notification including things like the values o开发者_运维技巧f form fields, session variables etc.

I have one that does it currently written by someone in house but it's not maintained and occasionally there are bugs in it causing give me only partial exception messages.

I tried googling it but all I could find were articles on how to write far more basic exception handlers than the one I have already.

Anyone know of any?

Have you looked at ELMAH, perhaps you can extend it to include your customizations.
