1 Introduction

The SOAP over WebSocket Protocol Binding Specification defines a binding of SOAP to the WebSocket protocol (as defined in [RFC6455]), including a WSDL transport URI and supported message exchange patterns (MEPs). This specification also defines a WebSocket subprotocol.

Note  This specification does not define any SOAP messages. Rather, it specifies how messages defined by a higher-layer protocol are formed and framed for transport over [RFC6455].


Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
