note 29798 added to function.session-start

if you are dealing with forms and session_start() you might experience that all form-values will automatically be emptied after returning to the form with the browser's back-button or javascript's history.back(). this is especially annoying if you want to enable your users to use the browser's back button to apply corrections to the inputted data on the previous page. add this line right after calling session_start() to solve the problem: header("Cache-control: private"); now, users can hit the back-button to access the form containing all the information they've inputted before. -- http://www.php.net/manual/en/function.session-start.php http://master.php.net/manage/user-notes.php?action=edit+29798 http://master.php.net/manage/user-notes.php?action=delete+29798 http://master.php.net/manage/user-notes.php?action=reject+29798
