What I generally use for no-cache is this:
<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">
Also, to force it to work correctly, I've seen people do stuff like this:
<HTML>
<HEAD>
<TITLE> Pragma No-cache </TITLE>
</HEAD>
<BODY>
This is an example of where to place the second header section<br>
so that the "Pragama, No-Cache" metatag will work as it is supposed to.<br>
</BODY>
<HEAD> <!-- Note the second header tag -->
<META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">
</HEAD>
</HTML>
Supposedly there are problems with the pragma no-cache method, which can be solved by adding an extra head-tag with the pragma meta setting, after the </body>
I've never tried that though.

I have set:- <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="Mon, 22 Jul 2000 11:12:01 GMT" in the header are of all my pages but still until the user does a reload in both IE & Firefox they do not see the new screen. Please tell me what else I can do to force the browser to not cache anything ever. I am not in a position of altering the client browser settings despite this being an intranet system.
