I can not seem to bind to HTTPApplication.Error event.

Goal:

1) Create an HTTPModule that will bind to the HTTPApplication.Error event.

2) After error occurs process it through a custom exception handler (utilizing Enterprise Library Exception Block)

--This allows us to configure different error handling processes and logging mechanisms without making code changes.

Problem:

Whenever an exception occurs HTTPApplication.Error never seems to fire!

What I've Tried:

1) Rearanging the module load order so that My exception handling module executed first, last, and in the middle.

2) Removed the default DNN Exception httpmodule (Thought DNN may have been swallowing the exceptions).

3) I have it running with the same code in a standard web app.

Any Ideas?
