Servers can then use this to inform their choices of what to push to clients. http://httpwg.org/http-extensions/draft-ietf-httpbis-cache-digest.html http://httpwg.org/http-extensions/draft-ietf-httpbis-cache-d... https://github.com/httpwg/http-extensions/pull/413 https://github.com/httpwg/http-extensions/pull/413

Hopefully this cannot be used to fingerprint clients!

  Not exactly fingerprint, but it may help to validate or not existing fingerprinting attempt. E.G: you identify user has being x, so you push a unique content to it, and tell to cache. Then later, you have a 62% of change some browser is user x. You just check if it's using the cached version of not. It will confirm at least if it's user x.
