HTTP 2.0 is the next planned version of the HTTP network protocol used by the World Wide Web. It is based on SPDY. HTTP 2.0 is being developed by the Hypertext Transfer Protocol Bis (httpbis) working group of the IETF. HTTP 2.0 would be the first new version of the HTTP protocol since HTTP 1.1 was described by RFC 2616 in 1999.
Goals for HTTP 2.0 are to improve the overall performance of the protocol while maintaining full backwards compatibility with the transaction semantics of HTTP 1.1. Performance improvements come from request-response multiplexing, header compression, and server push. It comes as an answer to the rise of SPDY, an HTTP compatible protocol launched by Google and supported in Chrome, Opera, Firefox, Internet Explorer 11 and Amazon Silk browsers.
The httpbis working group considered Google's SPDY protocol, Microsoft's HTTP Speed+Mobility proposal (SPDY based), and Network-Friendly HTTP Upgrade. In July 2012 Facebook provided feedback on each of the proposals and recommended HTTP 2.0 be based on SPDY. The initial draft of HTTP 2.0 was published in November 2012 and is based on a straight copy of SPDY.
