   Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and Routing
                   draft-ietf-httpbis-p1-messaging-24

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 provides an
   overview of HTTP architecture and its associated terminology, defines
   the "http" and "https" Uniform Resource Identifier (URI) schemes,
   defines the HTTP/1.1 message syntax and parsing requirements, and
   describes general security concerns for implementations.
