Pretty sure server push is being deprecated - current implementation is 'only half a feature', as clients lack the ability to tell the server what's already in cache.
In theory the client can cancel the response for a resource it's already got but by the time the response bytes reach the client it's really too late
- cm2187 8y agoYeah and if the client volunteers the list of all it has in cache it would result in some massive requests and a kind of quasi-cookie. I always found this feature interesting but weird.
- VBprogrammer 8y agoRandom thought. But isn't this a potential use for a bloom filter?
- youngtaff 8y agoYes bloom filters were a potential for Cache Digests, original prototype for Cache Digests used Golomb coded set as memory representation is smaller than Bloom filter https://github.com/h2o/h2o/issues/421 https://github.com/h2o/h2o/issues/421 But then Cache Digests moved onto Cuckoo Filters - https://github.com/httpwg/http-extensions/pull/413 https://github.com/httpwg/http-extensions/pull/413
