Session preserve

Hello! I am VERY new to php and i have a question (maybe it's pretty simple, but i couldn't get it work): I have a form page where i start a session. I cannot use php auth because the server does not run php as a module. Supposing the client has cookies disabled, please tell me how to propagate my session variables from the form page to another (i found that &SID can be used in url to preserve session id) but when i get to the other page (with header("Location: http://theserver/result.php?SID=$SID"), nothing is there but the SID variable. As you could probably figured out, i cannot allow to see the information entered in the form listed in url. So, please help me! thanks, Maxx maxx@mail.dntis.ro
