I came across a discussion on the issue of Dynamic CSS caching problem where it was suggested to append ?value to the end of the css file name for better caching. I am currently using themes and the css files are loaded automatically. Is it possible to use an HttpHandler to alter the css file path before rendering?
Are there any examples or resources available that demonstrate how this can be achieved?
If you are working with PHP, implementing the following code snippet would serve your purpose; however, it can be easily modified to work with any programming language.
<?php
$randNum = mt_rand();
?>
<link type="text/css" rel="stylesheet" href="style.css?<?=$randNum?>" />

UPDATE Another approach is to configure your headers to prevent caching. In the case of a CSS file, include the following snippet at the beginning of your CSS file, which should have a .php extension instead of .css:
<?php
header("Content-type: text/css; charset: UTF-8");
header("Cache-Control: no-cache, must-revalidate");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
?>
