Hello, I had an issue that I needed to be able to go back in the browser while in a session without getting "page has expired", I was reading through the manual and came across a comment about adding the following to the sessions page to allow users to traverse back: header("Cache-control: private"); (http://www.php.net/manual/en/function.session-start.php) This works fine on a Win32 dev box running Apache 1.3.x and PHP 5.0.3, but then I loaded the pages onto a RedHat box running PHP 5.0.3 on Apache 1.3.27. This box is running these pages through SSl (https) Anyone any ideas? Regards, Craig -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
