What does the question mark at then end of a css file mean/do?
- by Bob Dylan
I've noticed that on some websites (including SO) the link to the CSS will look like:
<link rel="stylesheet" href="http://sstatic.net/so/all.css?v=6638">
I would say its safe to assume that ?v=6638 tells the browser to load version 6638 of the css file. But can I do this on my websites and can I include different versions of my CSS file just by changing the numbers?
