       HTTP/1.1, part 3: Message Payload and Content Negotiation
                    draft-ietf-httpbis-p3-payload-19

Abstract

   The Hypertext Transfer Protocol (HTTP) is an application-level
   protocol for distributed, collaborative, hypertext information
   systems.  HTTP has been in use by the World Wide Web global
   information initiative since 1990.  This document is Part 3 of the
   seven-part specification that defines the protocol referred to as
   "HTTP/1.1" and, taken together, obsoletes RFC 2616.

   Part 3 defines HTTP message content, metadata, and content
   negotiation.
