Form Variables

Hi all, got an urgent problem.. it's regarding forms. my system works like this.. 1) user on page1 fills up form 2) upon clicking submit button, it will go to verify.php to verify if the entries are correct 3) if there is any errors, verify.php brings user back to page1 with all the errors listed beside the incorrect field entries my problem is: how do i make the user's browser remember the data they filled up at page1? i tried header("Cache-control: private"); but to no avail.. by the way, my page is a https:// page.. will appreciate all help! thank you in advance... hwee
