I have a shopping cart that is working completely fine in Firefox. In I.E., I can not get the page to display when hitting the back button. This may not necessarily be a PHP problem, but since moving to PHP session variables and not cookies, this error has popped up. In Firefox, I get the "POST DATA" message stating that post data has already been sent, blah blah blah. In IE, I get the "Page Can Not Be Display". I am just curious if anyone else has come across this and if they found a solution/cause. Thanks. Jason Walker
