Re: web.config - custom excption handling.

Brock,
  This is great.  I'm having a little issue with "HttpUnhandledException" (it 
tellls me that this is part of the .NET Framework infrastructure and is not 
intended to be used directly from code) but otherwise, this is wonderful.  It 
helped very much.  
Thanks again!

Well, I'm not familiar with the Exception App Block, but in ASP.NET you can
write a single bit of code for the entire application that will be notified
of unhandled exceptions. It's perfect for logging when your application
experiences a failure.

So, in global.asax:

void Application_Error(Object sender, EventArgs e)
{
   Exception ex = HttpContext.Current.Error;
   if (ex is HttpUnhandledException)
   {
      // The Excpetion was from the application (as opposed to something
from ASP.NET)
      ex = ex.InnerException;
   }

   // At this point, ex is the Exception that was the problem
   // ...
}

Once you have 'ex' from above, then you can write it to a log file, or the
event log, email to someone... Whatever. This is the typical pattern in
ASP.NET for tracking unexpected errors.

HTH
