    abstract =  {This document describes an optimised expression of the semantics of the HTTP protocol. The HTTP/2.0 encapsulation enables more efficient transfer of resources over HTTP by providing compressed headers, simultaneous requests, and unsolicited push of resources from server to client. This document is an alternative to, but does not obsolete RFC\{http-p1\}. The HTTP protocol semantics described in RFC\{http- p2..p7\} are unmodified.},
