nghttp2 - HTTP/2.0 C Library

This is an experimental implementation of Hypertext Transfer Protocol
|
|
|
|
|
version 2.0.

|
We started to implement HTTP-defat-04/2.0
|
|
|
|
|
(http://tools.ietf.org/html/draft-ietf-httpbis-http2-04) based on
|
|
|
|
|
spdylay code base.
|

|
|
|

|
|
|
The following features are not implemented:
|
|
|
|
|
|
2013-07-19 18:34:40 +02:00
|
|
|
* Header continuation
|
|
|
|
|
* PRIORITY frame handling
|
|
|
|
|
* PUSH_PROMISE and server-push in general
|
2013-07-16 17:08:05 +02:00
|
|
|
* Client connection header: spdycat and spdyd do not send/handle
|
|
|
|
|
client connection header.
|
|
|
|
|
* ALPN: spdycat and spdyd use openssl without ALPN support and still
|
|
|
|
|
uses NPN to negotiate HTTP-draft-04/2.0.
|
|
|
|
|
|
2013-07-19 18:34:40 +02:00
|
|
|
With those missing parts, the library is not still inter-operable
|
2013-07-16 17:08:05 +02:00
|
|
|
right now.
|
|
|
|
|
|
|
|
|
|
The spdycat and spdyd are (the names are now odd for HTTP/2.0) working
|
|
|
|
|
now assuming the above limitation. You can see the HTTP/2.0 frames
|
|
|
|
|
back and forth and connection-level and stream level flow controls.
