                    draft-ietf-httpbis-semantics-01

Abstract

   The Hypertext Transfer Protocol (HTTP) is a stateless application-
   level protocol for distributed, collaborative, hypertext information
   systems.  This document defines the semantics of HTTP: its
   architecture, terminology, the "http" and "https" Uniform Resource
   Identifier (URI) schemes, core request methods, request header
   fields, response status codes, response header fields, and content
   negotiation.

   This document obsoletes RFC 7231, RFC 7232, RFC 7233, RFC 7235, and
   portions of RFC 7230.
