Isn't having a 200 after a redeploy and 304 afterwards the behavior
we're looking for? What we want is that the browser always send a
request to the server to check if a new *.nocache.js is available, or
otherwise use the cached one (because there's no reason to download
the exact same file again). In other words, what we want is that the
browser does not *blindly* use a cached *.nocache.js, but instead
validate it against the server.

Or have I misunderstood what you're saying?
