Cache Busting with Query Strings

Question

I would like to know the best process for cache busting using query strings, I've read up on a few different sources but I still don't quite understand how to implement it..

If I reference a new file in my HTML header, e.g. "style.css?v=1.1", does that file have to be renamed to reflect the new appendage?

Or should I just leave the filename as "style.css" and let the server figure it out?

Thanks in advance.

My answer got deleted by mods even though it was legitimate...

You only need to add the iterative appendage to your code and there is no need to alter the actual file name.
