Unhandled Exceptions and Maximum request length exceeded

[=?Utf-8?B?Q2h1Y2sgUA==?=]

I have an HttpModule used for Unhandled Exception processing. The module
monitors both
application.Err or += new EventHandler(On Error); //regular UHE
AppDomain.Curre ntDomain.Unhand ledException += new
UnhandledExcept ionEventHandler (OnUhe); //UHE on threads
If I do a throw, the first one gets it.
If I do a throw in a thread, the second one gets it.

In each case I process the exception as follows:
HttpContext.Cur rent.Response.C lear();
HttpContext.Cur rent.Response.C learContent();
HttpContext.Cur rent.Response.W rite( a web page with pretty message);
HttpContext.Cur rent.Response.F lush();
HttpContext.Cur rent.Server.Cle arError();
HttpContext.Cur rent.Response.E nd();

This works fine for theads and throws.

When I was testing a file upload control and trying to upload a file greater
than
<httpRuntime maxRequestLengt h="4096" />
Both events fire and I get a generic web page that says:
"The connection to the server was reset while the page was loading."

How come I get both events and how come my pretty error page is not
displayed? I put in break points and the page creation stuff does get hit.
Actually the page creation code gets hit twice.

thanks,

in http there is no way to tell the browser to stop sending the request
other than closing the connection. as the browser could not complete the
request, it does not bother reading the response.
