SOAP Overview

SOAP consists of three parts:

•Encoding rules that control XML tags that define a SOAP message and a framework that describes message content

•Rules for exchanging application-defined data types, including when to accept or discard data or return an exception to the sender

•Conventions for representing remote procedure calls and responses

•SOAP messages define one-way data transmission from a sender to a receiver. However, SOAP messages are often combined to implement patterns such as request-response. When using HTTP bindings with SOAP, SOAP response messages can use the same connection as the inbound request
