How to get notified via email on error in your application

I am presenting here a simple but useful way to get notified via email, when ever an error is happening in your asp.net application with out using try catch. I am creating a httpmodule in app_code for notifying errors. Here is the code for the module.

Hurrey, so it is done. Cheers and Happy coding.
