Spdylay - SPDY C Library
|
|
|
|
|
========================
|
|
|
|
|
|
|
|
|
|
This is an experimental implementation of Google's SPDY protocol
|
|
|
|
|
version 2 in C.

|
|
|
The current status of development is in a beta stage now. As described
|
|
|
|
|
below, we can create SPDY client and server with the current Spdylay
|
|
|
|
|
API.

Build from git
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
Building from git is easy, but please be sure that at least autoconf 2.68 is
|
|
|
|
|
used.::
|
|
|
|
|
|
|
|
|
|
$ autoreconf -i
|
|
|
|
|
$ automake
|
|
|
|
|
$ autoconf
|
|
|
|
|
$ ./configure
|
|
|
|
|
$ make
|
|
|
|
|
|
|
|
|
|
Examples
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
*examples* directory contains SPDY client and server implementation
|
|
|
|
|
using Spdylay. These programs are intended to make sure that Spdylay
|
|
|
|
|
API is acutally usable for real implementation and also for debugging
|
|
|
|
|
purposes. Please note that OpenSSL with `NPN
|
|
|
|
|
<http://technotes.googlecode.com/git/nextprotoneg.html>`_ support is
|
|
|
|
|
required in order to build and run these programs. At the time of
|
|
|
|
|
this writing, the Beta 2 of OpenSSL 1.0.1 supports NPN.
|
|
|
|
|
|
|
|
|
|
SPDY client is called ``spdycat``. It is a dead simple downloader like
|
|
|
|
|
wget/curl. It connects to SPDY server and gets resources given in the
|
|
|
|
|
command-line::

SPDY server is called ``spdyd``. It is a non-blocking server and only
|
|
|
|
|
serves static contents. It only speaks ``spdy/2``::

Currently, ``spdyd`` depends on ``epoll`` facility which only exists
|
|
|
|
|
in Linux. I'll add ``kqueue`` support.
