Page Expiration Problem

[Anon]

Hi,

If I type something into a search form, submit it, get results from a php query, click on one of the results to go to a specific page for that result, and then try to go back to the original search results page by clicking the "Back" button on my browser I get a "Warning: Page Expired" message. How can I avoid this warning and just back the search results page without rerunning the PHP query? When I shop at sites like amazon.com I never get such warnings, so there must be some way around it.

Thanks for all your help,

Sonny

You're running IE, aren't you ? I've had this annoying message too. I noticed that it disappears if you use GET method for your form. Another possibility in your case is to use target=_blank links, which eliminates the need to use the back button. If someone knows when exactly this message appears (timeout ?) and how to suppress it properly (if possible), I'll be glad to know.
