this being an intranet system.

What I generally use for no-cache is this:

This is an example of where to place the second header section

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,

Alf

I had a similar problem trying to expire pages so that the user received
a "Page Expired" message when they clicked on the back button. I
discovered that if you set Cache-control to no-cache then Firefox/IE
ignore the expires date. The solution that I got working on IE7 was to
set Cache-control to must-revalidate and Expires to 1 second into the
future.

Firefox still didn't do what I wanted and I didn't test IE6.

PS: I was doing this through HTTP headers.

Why write stuff that's already written? :)
