> h2. Overview
> Support HTTP/2 as a client side L7 protocol. This feature is implemented into 
> ATS core.
> Now, it supports the latest HTTP/2 draft version, h2-16.

> h2. How to test
> # Build ATS codes normally. you need neither any build option nor external 
> HTTP/2 library.
> # Configure settings to use https.
> # Add settings to records.config to use http2.
> {noformat}
> CONFIG proxy.config.http2.enabled INT 1
> {noformat}
> # Access to ATS by HTTP/2 client.

> h2. Overview
> We, CDN team of Yahoo! JAPAN, have implemented HTTP/2 support in ATS core 
> experimentally.
> Now, it supports HTTP/2 draft-12.
> http://tools.ietf.org/html/draft-ietf-httpbis-http2-12
> 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=' 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.
> ** it'll refer to configuration settings for SPDY on TS-2740
