Tengine added SPDY/3 support to this module. The new directives are listed below.

Directives

Syntax: spdy_version [2|3] Default: 3 Context: http, server

Specify the version of current SPDY protocol.

Syntax: spdy_flow_control on|off Default: on Context: http, server

Turn on or off with SPDY flow control.

Syntax: spdy_init_recv_window_size size Default: 64k Context: http, server

Specify the receiving window size for SPDY. By default, it's 64K. It will send a WINDOW UPDATE frame when it receives half of the window size data every time.

Syntax: listen address[:port] [spdy_detect] [ssl]

Default:

Context: listen directive

Server can work for SPDY and HTTP on the same port with this directive. Note that the server will examine the first byte of one connection and determine whether the connection is SPDY or HTTP based on what it looks like (0x80 or 0x00 for SPDY).

Server will listen on port 80 for SPDY and HTTP, for example:

listen 80 spdy_detect;

Server will detect whether SPDY or HTTP is used without using a TLS extension (NPN), for example:

listen 443 ssl spdy_detect;

Server can detect whether SPDY or HTTP is used directly, and also it can negotiate with client via NPN, for example:

listen 443 ssl spdy_detect spdy;

Note

Removed spdy module after the Tengine-2.2.0.
