Warning: Page has Expired "help"

I get this message while clicking on Previews and using history.back()

Warning: Page has Expired The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you.

To resubmit your information and view this Web page, click the Refresh button.

How can I work around this? I know what the message means but I need to build the page up with the form info.

I can't find anything about this, probably couse I don't yet know where to look.

I usually store the post info and use a header or javascript's location.replace() to redirect to the next page. That way, the form submission is overwritten in the client's history.

If u need to build the page directly with the post data I'm afraid there's no way around this problem.
Not that I know of.

The problem cannot be completely avoided but you can at least mitigate it a little by adding the following to your code.

// to retain cache in IE back button
header("Cache-Control: Public");

It will work for IE but not v4.x of Netscape.

Add it at the top of your page before any output or you'll get an error. You can add session information first and then the header but nothing else.

HTH

Ok thanks a lot I'll try both the java script and the php header

I had the exact ame problem on certain pages (usually when going back to a page that had a form submitted to it).
Anyway it turned out to be the cache setting in php.in:

session.cache_limiter = nocache (change to private or public)
