PFP: Cache Digest #131

Closed Jxck closed 5 years ago

Jxck commented 5 years ago

Request for Mozilla Position on an Emerging Web Specification

Other information

in httpwg at IETF, chair mnot asking implementation signal for cache digest now.

https://lists.w3.org/Archives/Public/ietf-http-wg/2019JanMar/0033.html

if mozilla says interested in or not, thats big material to consider this spec is dead or alive.

personally, I'm looking forward to use Cache Digest for Optimize http2 push. if cache digest will dead, that means cache aware server push for browser dead too. so I wanna hear good voice from firefox.

I strongly suspect mnot already talked to someone at Mozilla given that email...

Considering our cache implementation, this is not easy to implement. It is rather large machinery and the win from push is ~ 1-rtt.

martinthomson commented 5 years ago

This is an experimental RFC, which is sometimes not an indication that it's out there. This one is truly out there. More effort is being spent on 103 I think. Which reminds me...

It's not actively harmful, so non-harmful is probably a reasonable position, but given the complexity of implementation, it's probably not something we'll end up doing. The recent addition of cuckoo filters means that it is less difficult to do without complete walks of the cache, but it still is far from trivial.

I'd note that #133 has a few comments that are discussing the substance of the position and thus probably should have been here instead.
