This is the home page for HTTP/2, a major revision of the Web's protocol. It is maintained by theIETF HTTP Working Group.
What is HTTP/2?
HTTP/2 is a replacement for how HTTP is expressed “on the wire.” It isnot a ground-up rewrite of the protocol; HTTP methods, status codes andsemantics are the same, and it should be possible to use the same APIs asHTTP/1.x (possibly with some small additions) to represent the protocol.
The focus of the protocol is on performance; specifically, end-user perceivedlatency, network and server resource usage. One major goal is to allow the useof a single connection from browsers to a Web site.
The basis of the work wasSPDY, but HTTP/2has evolved to take the community’s input into account, incorporating severalimprovements in the process.
