Versioning css/javascript in Wordpress

Question

I 'm trying to grasp the concept of versioning css/js files.

<link rel="stylesheet" href="/css/base.css?version=1234" type="text/css" />

This method will actually prevent the file from being cached, period! This is bad.

What is the best practice of doing this in Wordpress? I'm confused...

Answer 1

That's not how it works in my experience. Browsers do cache based on GETs. To test this, go to the author's url (http://static.prelovac.com/style.css?1266235697) with firebug enabled. First request should give you "200 OK", now refresh and you get "304 Not Modified".

If you're not convinced, you can always try this method
