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
|
2013-07-22 16:31:32 +02:00
|
|
|
* ALPN: ``nghttp`` client and ``nghttpd`` server use OpenSSL without ALPN
|
|
|
|
|
support and still use NPN to negotiate ``HTTP-draft-04/2.0``.
|
|
|
|
|
* HTTP Upgrade dance
|

|
|
|
|
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 ``nghttp`` client and ``nghttpd`` server are working now assuming
|
|
|
|
|
the above limitation. Both programs start HTTP/2.0 with `prior
|
|
|
|
|
knowledge
|
|
|
|
|
<http://tools.ietf.org/html/draft-ietf-httpbis-http2-04#section-3.4>`_
|
|
|
|
|
or TLS NPN negotiation. No HTTP upgrade dance is supported yet. You
|
|
|
|
|
can see the HTTP/2.0 frames back and forth and connection-level and
|
|
|
|
|
stream level flow controls.
