Abstract

This document specifies a framework for adding compression functionality to the WebSocket Protocol [RFC6455]. The framework specifies how to define WebSocket Per-Message Compression Extensions (PMCEs) for a compression algorithm based on the extension concept of the WebSocket Protocol specified in Section 9 of [RFC6455]. A WebSocket client and a peer WebSocket server negotiate the use of a PMCE and determine the parameters required to configure the compression algorithm during the WebSocket opening handshake. The client and server can then exchange data messages whose frames contain compressed data in the payload data portion.

                   Compression Extensions for WebSocket

Abstract

   This document defines a framework for creating WebSocket extensions    that add compression functionality to the WebSocket Protocol.  An    extension based on this framework compresses the payload data portion    of WebSocket data messages on a per-message basis using parameters    negotiated during the opening handshake.  This framework provides a    general method for applying a compression algorithm to the contents    of WebSocket messages.  Each compression algorithm has to be defined    in a document defining the extension by specifying the parameter    negotiation and the payload transformation algorithm in detail.  This    document also specifies one specific compression extension using the    DEFLATE algorithm.
