RE: [PHP-DB] 'Page can not be displayed' when hitting the back button

In case anyone comes across this in the future, I finally found a solution to this: php.ini Find session.cache_limiter and make sure the setting is set to public or private. "nocache" was the problem. Does anyone have any concerns about this setting? I am looking around to see if this causes any security issues. I did find some stuff about this affecting downloads, but there are no downloads through PHP pages. Thanks. -----Original Message----- From: Jason Walker [mailto:jwalker@desktophero.com] Sent: Sunday, February 13, 2005 7:17 PM To: php-db@lists.php.net Subject: [PHP-DB] 'Page can not be displayed' when hitting the back button 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
