I don't know. You have to be concerned about firewalls, though,
not just browsers, and I don't begin to have access to all of them.

I'm not sure it *always* does.

HTTP 1.0 specifies "pragma" as a header to be sent by clients 
when requesting a fresh copy of a page, not by servers. 

Can you name *any* circumstance in which the illegal "pragma" 
header works and these headers don't?
<META HTTP-EQUIV="Expires" CONTENT="Thu, 01 Dec 1994 16:00:00 GMT">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
