    abstract =  {This specification describes an optimised expression of the syntax of the Hypertext Transfer Protocol (HTTP). The HTTP/2.0 encapsulation enables more efficient transfer of representations by providing compressed header fields, simultaneous requests, and also introduces unsolicited push of representations from server to client. This document is an alternative to, but does not obsolete the HTTP message format. HTTP semantics remain unchanged.},
