An HTTP Extension Framework
RFC 2774, “An HTTP Extension Framework”, is a Historic document published in February 2000 by H. Nielsen, P. Leach, S. Lawrence. The canonical text is published by the RFC Editor.
Abstract
A wide range of applications have proposed various extensions of the HTTP protocol. Current efforts span an enormous range, including distributed authoring, collaboration, printing, and remote procedure call mechanisms. These HTTP extensions are not coordinated, since there has been no standard framework for defining extensions and thus, separation of concerns. This document describes a generic extension mechanism for HTTP, which is designed to address the tension between private agreement and public specification and to accommodate extension of applications using HTTP clients, servers, and proxies. The proposal associates each extension with a globally unique identifier, and uses HTTP header fields to carry the extension identifier and related information between the parties involved in the extended communication.
What “Historic” means
A specification that has been superseded or is otherwise no longer recommended for use.
