Hm, are you sure? I've seen some really odd behavior with IE5
not obeying caching directives. Particularly annoying is that both NS
and IE seem to always cache POST arguments no matter whether the pages
before and/or after the POST are no-cached.

Hm, I didn't have the no-store header, and from what you said,
the expires header actually caused a problem? I'll have to try it
this way.
