A:
It's a query string. It can be parsed by server-side processes for allowing variable parts of the stylesheet, or it can be used to disable caching by browsers or proxies.

It's a way to control caching. When the value of the "v" parameter changes, the browser will consider it a different URL and ask for a new copy of the file instead of using its cached copy. This technique is often used to "version" static files by providing something like a timestamp in the query string that marks when the file was last changed.

Yes, and to answer the second part of your question that you added, it has to do with the web server and the HTTP request, not which server side scripting language your site uses. It can be used anywhere.
