Technical Summary This specification describes an optimized expression of the semantics of the Hypertext Transfer Protocol (HTTP). HTTP/2 enables a more efficient use of network resources and a reduced perception of latency by introducing header field compression and allowing multiple concurrent messages on the same connection. It also introduces unsolicited push of representations from servers to clients. This specification is an alternative to, but does not obsolete, the HTTP/1.1 message syntax. HTTP's existing semantics remain unchanged. Review and Consensus We have enjoyed active participation from a broad community, including browser vendors, intermediaries (such as CDN and proxy vendors), server vendors and protocol library authors; this includes both commercial vendors and open source libraries. Our current implementation list is at: https://github.com/http2/http2-spec/wiki/Implementations Additionally, we have had participation and review from the non-implementing HTTP community itself. We have substantial external interest from the Web performance community as well. We have also coordinated with the W3C, giving them regular updates through the liaison and the TAG. See the document shepherd writeup for a detailed discussion of the tricky points: <http://datatracker.ietf.org/doc/draft-ietf-httpbis-http2/shepherdwriteup/> Personnel Mark Nottingham is the Document Shepherd and Working Group Chair.
