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:

A note on caching:

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,
