Hey guys, I coded a php script that includes a FULLTEXT search that is through a $_POST form in PHP. It works great, however after the search, the user clicks on the result (which links to another page)... but then when they hit the back button.. they get a:

Warning: Page has expired. (Internet Explorer)

I notice that a lot of websites do this (ie. Amazon.com)... but I find it annoying. I certainly have been to websites that do not have this problem. Any ideas how to avoid it? or what causes it? Thanks and merry xmas!

See what happens when you switch from $_POST to $_GET

Yeah, I don't know the exact reason why this happens, but it seems to happen to me when using sessions. It will be because of security or something.
