SPDY Protocol

SPDY is an open networking protocol for transporting web content, it adds a session layer atop of SSL that allows for multiple concurrent, interleaved streams over a single TCP connection.
The usual HTTP GET and POST message formats remain the same; however, SPDY specifies a new framing format for encoding and transmitting the data over the wire.
