The WebSocket protocol enables two-way real-time communication between clients and servers in situations where direct access to TCP and UDP are not available (for example, from within Javascript in a web browser). This document specifies a new WebSocket sub-protocol as a reliable transport mechanism between MSRP (Message Session Relay Protocol) clients and relays to enable usage of MSRP in new scenarios. This document normatively updates RFC 4975 and RFC 4976.
