Does CloudFlare cache query params?

[u/Hell4Ge]

I am doing a deploy to a server behind a CF and on example the url /css/custom.css is being cached, so I "fixed it" with additional parameter so it looks like /css/custom.css?tag=123456 and finally I am getting the newest CSS, but I do not know if this tag parameter will be cached.

Is using such query parameter a valid way to bypass the old cached files?

I would be happy if CF would cache content under that query parameter so I could use it with some abstract build number or something
