IE caching pages it shouldn't

[John Dalbec]

I'm using IMP 3.2.2 from the Horde project (www.horde.org).
If I log in to IMP and log out again, I can see pages from
when I was logged in using the back button. How do I get
IE not to cache those pages? My server is sending

Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate,
post-check=0, pre-check=0
Pragma: no-cache

but IE is still caching the page. Only the pages where I'm
actually logged in are cached, though. The login page is
not cached (or at least IE requests a fresh copy from the
server) and the page after I logout (actually that's also
the login page) is not cached. At least the initial
mailbox page is a redirect. Maybe that's confusing the
caching mechanism?

Thanks. I had tried these and they didn't appear to be
working but then I discovered that my test server was
redirecting to my production server. Once I fixed that, it
worked fine.
