CSS Cache Buster

CSS Cache Buster does one very simple but very powerful thing: it ensures that your
Wordpress blog delivers the very latest version of your CSS stylesheet to your
visitors, no matter how often or how rarely your edit for CSS.

You no longer need to worry that you’ve made a CSS change that others won’t see
because of caching issues at their end.

Technically, this plugin automatically appends a last-modified date/timestamp to
the end of your stylesheet url.

And since this feature is applied as a filter, you don’t have to touch your theme
files. It just works.

Simple!
