This is really interesting thanks. Doesn't this lead to the most highly used static assets being pushed for every subsequent request? Isn't that wasteful? I use varnish cache extensively and am considering writing a probabilistic server push module. It could keep track of subsequent requests and push the next set of assets. This is more of a server module approach rather than client side. Any thoughts on that?
