If you want to avoid round-trips, version the URI
("login-20160628.js") and send Expires. If you want to keep the URI
("index.html"), send Last-Modified and ETag.
I don't think there can ever be a magic bullet (in 1.x, without server

best practices and user expectations should be pretty well established
by now.
