Hi all

This is a very important issue in PHP
In PHP suppose you submit a form from say "form1.php" and get a page say "result1.php" as a result of the form submiited by form.php.

now result.php was generated using the information provided in form.php
again you go to any other page say page3.php
and you click on the back button in the Browser (IE Netscape warns first and then takes you to the previous page) the page you get says that
The page is expired this page was generated using the info you provided in a form
and IE doesn't resubmit the form automatically

Now I solved this problem by writing
session_cache_limiter('public');
in the result.php page before starting the session

but now the problem is if i go to this page the browser generates the page from the temporary internet files of my system as the session_cache_limiter caches all the pages in the Browser side
so each time i do modification in the pages i need to delete files from the internet options and refdresh again
Can any body help me?????????????

Use header() to redirect the user after the form is submitted. This will prevent IE from asking to resubmit POST data when back button is pressed.

But the posted data will not be available in the page where we redirect to using header() function.

Do header() AFTER you have processed the POST data
