"you should almost certainly be using static files to deliver JS.  This is
the ONLY guaranteed way to cache-bust across ALL browsers."

Sorry for my ignorance, but I am in foreign zone with the JS stuff and
need a bit more info.  When you say that we should use static files to
deliver Javascript, how do we do that?  Server config or browser config? 
I imagine server, but then my next question would be how? In apache?
