There is a demo of how to do this here: How can i do a expires to my page or here How to code security for Expires Page or here printing header method.

Hope that helps. Sadly some browsers don't play fair and ignore expires, cache-control and pragma no cache directives but what can you do. Only so much and this is it.

cheers
