Page Expired Warning

[Jordan]

I would like users to see the standard "page expired" warning when they
click the Back button.

I've searched on web, but haven't been able to find a solution for this.

Any suggestions?

Thanks!

set the expiry header in the past so that when they click back the
browser informs that the page has expired

I found a couple of examples of this, but haven't been able to get it to
work yet.

Wouuld you happend to have an example?
Thanks!

I tried adding this:

<%@ OutputCache location="none" %>

Also, I tried adding these meta tags:

<meta http-equiv="Expires" content="-1">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Cache-Control" content="no-cache">

None of the mentioned means can remedy the problem. You have to prevent
the user from resubmitting a POST request.

See this discussion http://tinyurl.com/bcekb for example.
