RE: [Zope] Does Zope Cache Pages?

proxies. IE < 5.5SP1 never sends a 'Pragma: no-cache' header when you press Reload.

That's a server-generated header, not a browser one, so IE would never send it to anyone. If you're saying that IE responds incorrectly to that header (or the equivalent meta tag), it looks to be true under certain circumstances: Bug in IE and awkward (illegal HTML) workaround: http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q222064& A note on caching: http://support.microsoft.com/default.aspx?scid=kb;en-us;Q234067 Also, "Pragma: no-cache" is an old HTTP 1.0 header (which is probably why it's handled badly with transparent proxies). I've successfully used "Expires:0" with Zope pages and IE browsers to force a reload. Cheers, Julian.
