On a couple of pages I have, each page uses an include file that writes a couple of session variables.
Each page has its own post form. It's a "signup" site.
Everything goes well until I click the Back button at some point.
Then I get this message in IE5 (not a PHP error):
"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. "
You must have seen these errors before.
And it is happening because the browser can't remember the form input, for a Back move, so you have to reload the page.
Grateful for advice!
