Hello there, I'm currently looking into implementing the SPDY [1] protocol based on Warp. I read in the archives that Daniel Sommermann wanted to start something similar for snap-server but I haven't seen any updates for some time. So if you've got a finished implementation somewhere in your drawer this would be a great time to publish it ;) Otherwise I'd start with the parser for the framing layer. SPDY compresses some parts of the frames using zlib. Michael already merged a small patch I wrote into zlib-bindings to support initial dictionaries so I think I'm ready to go there. Another thing that is needed to fully support SPDY is TLS. I think I'd use the tls library by Vincent here. There is some implementation work needed in the library for an extension called NPN (next protocol negotiation) which SPDY uses. Vincent offered to help here. Thanks :) (By the way, although it's possible to force at least Chrome to use non-encrypted connections "it'll break all sorts of things" according to the SPDY book [2]). With this post I'd like to start a discussion about the implementation and interfaces of this so the result can be reused in other contexts (e.g. for Snap). If you've got any suggestions and sources of inspiration I'm happy to hear them. Best regards, Robin [1] http://dev.chromium.org/spdy [2] http://spdybook.com/
