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 very early stage. But there is a demo program spdycat in examples directory, which can connect to SPDY-capable server via SSL and select spdy/2 with NPN and get a resource given in the command-line:

$ ./spdycat -vn https://www.google.com/
[  0.023] NPN select next protocol: the remote server offers:
  * spdy/2
  * http/1.1
[  0.034] send SYN_STREAM frame (stream_id=1, assoc_stream_id=0, flags=1, length=83, pri=3)
  method: GET
  scheme: https

  user-agent: spdylay/0.0.0
  version: HTTP/1.1
[  0.082] recv SYN_REPLY frame (stream_id=1, flags=0, length=580)

[  0.083] recv DATA frame (stream_id=1, flags=0, length=2426)
[  0.084] recv DATA frame (stream_id=1, flags=0, length=4096)
[  0.091] recv DATA frame (stream_id=1, flags=1, length=3114)
[  0.091] send GOAWAY frame (last_good_stream_id=0)

Please note that OpenSSL with NPN support is required in order to build and run spdycat.

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
