Has anyone used this and found it helpful?
For dynamically generated pages, yes, but is there any advantage for static pages that happen to be
PHP?
From a good caching tutorial at:
http://www.mnot.net/cache_docs/#IMP-SCRIPT
The header cited:
<code>
<?php
Header("Cache-Control: must-revalidate");
$offset = 60 * 60 * 24 * 3;
$ExpireString = "Expires: " . gmdate("D, d M Y H:i:s", time() + $offset) .
" GMT";
Header($ExpireString);
?>
</code>
Thanks!
