[SOLVED] Stopping form re-submission via the Back button w/PHP

[kjtocool]

I have the following code, but telling it to re-validate apparently doesn't work, because it's re-submitting every time someone hits the back button.  Any ideas?

 

<?php
header("Cache-Control: must-revalidate");
session_start();

[kjtocool]

Blah, apparently my problem was the header statement needs to come AFTER the my session statement?

 

Working now.
