I am a bit confused. I have built a web site from dynamic pages using PHP & Mysql. When a user selects an item from a drop down list that takes then to a detail page. When they click back on the browser button they get a message about the page has expired.
Is this an issue of session or cookie? How do I correct this ? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
