I've created my own version of
UnhandledExceptionModule independantly of
codePlex project in 2007,
I've used code from http://support.microsoft.com/kb/911816
with considerations from http://www.eggheadcafe.com/articles/20060305.asp
and done some refactoring. It also allows to use AppSettings["EventLogSourceName"]
The zip file also includes TestUnhandledExceptionWAP test project, that I used to investigate issue
