On Wikimedia Polska wiki we have a problem with .js and .css pages - when we made some changes, we have to wait a few hours/days to see result. This problem is not with browser cache, but cache from server side.
(For example on Polish Wikipedii changes made in .css and .js pages are visible immediately.)
ResourceLoader should address this and other JS/CSS caching issues, and is slated to be deployed next week, so let's wait for that and check back on this issue after the deployment.
