   Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and Routing
                   draft-ietf-httpbis-p1-messaging-26

Abstract

   The Hypertext Transfer Protocol (HTTP) is a stateless application-
   level protocol for distributed, collaborative, hypertext information
   systems.  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 related security
   concerns for implementations.
