This new Hyper Text Transfer Protocol 2.0 draft was published yesterday and measures 52 pages in length. HTTP 2.0 is about being more efficient as well as offering new features not found in HTTP 1.1.
To find out more details or to read the draft, stop by w3.org. Embedded below is the abstract for this updated HTTP protocol presently under development.
This specification describes an optimized expression of the syntax of the Hypertext Transfer Protocol (HTTP). The HTTP/2.0 encapsulation enables more efficient use of network resources and reduced perception of latency by allowing header field compression and multiple concurrent messages on the same connection. It also introduces unsolicited push of representations from servers to clients.
This document is an alternative to, but does not obsolete the HTTP/1.1 message format or protocol. HTTP's existing semantics remain unchanged.
This version of the draft has been marked for implementation. Interoperability testing will occur in the HTTP/2.0 interim in Hamburg, DE, starting 2013-08-05.
