IE has some strange caching policies. By saying "when the user JUST
comes back ..." do you mean "when he hits the [back]-Button or uses
javascript:history.back()" ? In this case, IE5.5 applies some kind
of timeout-rule: if you hit "back" within a short intervall, it will
display the cache, no matter how hard you try to tell it "don't do that".
After some time has passed, it will reload the page upon going back.
BTW, same problem if you type in an URL in the address-line: the cache
will be used.
You may look up this problem in php- or perl-related mailing-lists, there
seems to be no other solution then the already mentioned "pragma",
"cache-control" and "expiry-time"-headers.

Betreff: Re: Cache problem with IE
I have the problem under Windows (I don't have Mac).
My goal is: when the user just comes back to a (JSP) page I want the
page executed again to show up to date information.
