Getting slightly off topic, but I'm confused about an aspect of server push (maybe you can help). Even on HTTP/1, the client typically only downloads assets on the first page load for a given website, then it caches them. Subsequent requests for other pages are much quicker because the assets don't need to be downloaded again. With server push, would the server typically send all linked assets on every request? Or can it somehow keep track of which clients have cached which assets, and avoid wasting bandwidth?
