I have a CSS file that is included on every page of my website. Is there a way I can force this file to refresh it’s cache via the file itself? I have so many pages so it would be so time consuming to add a versioning attribute to the end of the include.
It can be automated server side.
$csstime = date ("Y-m-d\TH-i", filemtime($_SERVER["DOCUMENT_ROOT"] . '/css/style.css'));
<link rel="stylesheet" type="text/css" href="css/style.css?update=<?php echo $csstime ?>">
This will cache, but refresh when changed.
