Force Brower To Refresh/ReDownload Page

Here is a very small snippet that will require the browser to re-download the page despite if it is cached or not.

It's useful if you content or images constantly changing that aren't recognized without a hard refresh or clearing the cache.

PHP:

<?php

header("Cache-Control: must-revalidate");

?>
<!-- REST OF THE PAGE BELOW - INCLUDING OTHER PHP -->

Wow, I never knew this code, nice contribution!

Cheers, most of my work is using my knowledge, then building on it by experimenting with certain functions.
