What extra parameters have you added to the request? AFAIK the
standard solution to this type of "improper caching" problem is to
simply append a random number or a timestamp to the request URL. It's
an ugly hack, but it does work even when the headers don't seem to do
the trick.
Of course, the "Right Way" is to rely on the no-cache headers, so you
might want to do a bit more troubleshooting on that front.
Hope this helps,
