when a System.Web.HttpResponse.End() is called a System.Thread.Abort is being fired, which i'm guessing is (or fires) an exception? I've got some logging and this is being listed in the log file...

Is this normal behavior and is it possible to gracefully abort instead of (what looks like) a sudden abrupt abort?
So far it the common census that it's by design. So i'm wondering if it's possible we could take this question and see if we could tweak the code to make it not feel like we're ending the thread prematurely and gracefully exit ... Possible? Code examples?
There is no such thing as a "graceful" abort. You could simply Flush() the response, though, instead of ending it and let the framework take care of closing the connection for you. I'm assuming in this case that you want the response sent to the client, i.e., the typical case.
According to MSDN, calling Response.End() throws the ThreadAbortException when the response ends prematurely. You really should only call Response.End() when you want the exception raised.
