This is great information. One thing that I have noticed is that with IE the responses are cached when using a GET method in the HTTP request. If you use POST then the responses are not cached. It sounds like adding the no-cache headers fixes the problem too. I have not tested GET vs. POST with Opera but it might be worth a shot.
