I have a similar issue in that I want to catch the 'Maximum request length exceeded' exception within the Application_Error handler and then do a Redirect.

(The difference is that I am writing a REST service with ASP.Net Web API and instead of redirecting to an error page, I wanted to redirect to an Error controller which would then return the appropriate response).

However, what I found was that when running the application through the ASP.Net Development Server, the Response.Redirect didn't seem to be working. Fiddler would state "ReadResponse() failed: The server did not return a response for this request."

My client (Advanced REST Client for Chrome) would simply show "0 NO RESPONSE".

If I then ran the application via a local copy of IIS on my development machine then the redirect would work correctly!

I'm not sure i can definitively say that Response.Redirect does not work on the ASP.Net Development Server but it certainly wasn't working in my situation.

So, I recommend trying to run your application through IIS instead of IIS Express or the Development Server and see if you get a different result.
