Hi,

I have a script dyanmically generated web pages. At bottom of each new page is a "Next" button, which submits to the script and displays the next page in the series.

Also there is a "Back" button which performs a JavaScript history.back() command (oops - hope i put this in the right forum).

Anyway, a lot of people are getting "page expired" messages when they use my back button and/or the browser's own back button.

Why is this happenning? And can I fix this issue? Thanks in advance...

are you sending no-cache headers or expiration headers?

you can try this, not sure if it will work though:

<?php
    @header(\"Expires: \" . gmdate (\"M d Y H:i:s\",time() + 8640000));
?>
