Apologies if this has been covered already, I have tried to find it...
I have a site where I want people to be able to go from search results to individual items and return to search results without resubmitting.
The problem at the moment is that with either the back button I've provided or the navigator back button when I try and go from an individual item back to search results I get:
"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. "
It seems like there ought to be a simple way to make sure this caches ... or is it to do with using GET not POST? Any advice welcome.
I'm using PHP 4.1.2 with MySQL
