Masakazu Kitajo commented on TS-2729:
-------------------------------------
I agree that current implementation for HTTP2 needs lots of improvements and
fixes. However, if both implementations (SPDY and HTTP2) have same issues, I
think they are fixed in same way and same time (and we should integrate common
logics).
So my suggestion is that fix critical problems, put it into some branch or
master, and improve the both implementations with many other developers.
Attaching many patches on to one ticket would not work well, we should file
separate tickets for each issues (like tickets for SPDY).
> Add HTTP/2 support to ATS

> h2. Overview
> We, CDN team of Yahoo! JAPAN, have implemented HTTP/2 support in ATS core
> experimentally.
> Now, it supports HTTP/2 draft-10.
> http://tools.ietf.org/html/draft-ietf-httpbis-http2-10
> Our implementation similar to the SPDY implementation in ATS core(TS-2431)
> but we use nghttp2 library instead of spdylay to interpret HTTP/2 frames.
> https://github.com/tatsuhiro-t/nghttp2
> We tested NPN and ALPN negotiation.
> h2. How to test it
> * Install nghttp2 library, here is URL of this library:
> https://github.com/tatsuhiro-t/nghttp2
> * Use '--enable-http2' option to compile ATS:
> {noformat}
> $ ./configure --enable-http2
> $ make all && make install
> {noformat}
> * You can use '--with-openssl=<dir>' option.
> * Need not configure anything if you just want to test HTTP/2 without SSL.
> The code can recognize HTTP2, SPDY or HTTP by reading first to 3rd bytes of
> requests.
> * You can use nghttp in nghttp2 library(or other HTTP/2 client) to request,
> for example:
> {noformat}
> # HTTP/2 without SSL
> $ nghttp -v http://localhost/b.txt
> # HTTP/2 + SSL
> $ nghttp -v https://localhost/b.txt
> {noformat}
> h2. TODO
> * Cleanup codes.
> * Follow http2 draft-12 and later.
> * -Support ALPN.-
> * Add settings related to HTTP/2 into records.config.
