Simple Object Access Protocol Routing Protocol (SOAP-RP) is a stateless protocol for the exchange of SOAP messages. In addition to simple one-way messages, an optional reverse message path makes two-way (like request/response, return of acknowledgements or return of faults) and peer-to-peer (P2P) messaging possible. It is expressed as a SOAP header entry within an envelope, and is independent of underlying protocols.

SOAP-RP may be used with Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) using Direct Internet Message Encapsulation (DIME) for encapsulation, or with Hypertext Transfer Protocol (HTTP) or other underlying protocols.
