But when I click then back link ,I lost the data in the form . So I change the session_cache_limiter = private or public. That when I back I can got the data in the form. And I have a new problem,I need check the session in my program when the different user login(I check use status using session ) , When I login use different user ,the session I got is not correct. And I found I can't destroy the session.What shall I do? What is the different about nocache,private,public? -- Edit Bug report at: http://bugs.php.net/?id=11618&edit=1
