HttpModule Error Handler Stuck In Loop

[Dan Sikorsky]

I use an HttpModule that handles unhandled exceptions from an .aspx.cs page
by logging to a text file, logging to the event viewer's app log, and sending
out an email to the website developer and any interested parties. Finally, a
user friendly page (GenericError.a spx) is Redirected To.

My Page_Load event has no code, so when the page is unavailable, (for
instance, the website is down), an unhandled event is generated and my
HttpModule is called. Everything is executed as listed above, but the
redirection to GenericError.as px generates another unhandled exception
(because the website is down), and thus we enter into a loop.

I end up with 14000+ email messages, and so does everyone specified in a
web.config list.

The only fix I can see is to put a try/catch block in every Page's Page_Load
event.

Is there some smarter way to handle this?

HttpRequest request = Context.Current .Request;
if (string.Compare (request.LocalP ath, "/GenericError.as px", true))
{
Context.Current .Response.Write ("An unhandled error occurred");
Context.Current .Response.End() ;
}
//should be safe to redirect to GenericError.as px

Where do I place this code?

Should it go just before the redirect to GenericError.as px in the HttpModule?

The problem is redirecting to GenericError.as px which is in the website that
is down, resulting in firing the HttpModule again.

I see it now. The code goes in at the top of the HttpModule to protect
against being called by the GenericError.as px, which was already called by
the HttpModule.
