OFFTOPIC: Making a page expired

[Matt Krevs]

I am trying to get the browser to display the "this page has expired"
message when the user hits the Back button on the browser.

We have the luxury? of only needing to support IE5.5. No matter what meta
tags i use I cant seem to get the browser to display the standard "this page
has expired" message.

This is especially important in the situation where the user's session has
expired and the user then uses the back button and tries to click on a
hyperlink on the old page.

Any ideas?
