How Does SOAP Work?
Client packages remote operation call as XML message.
- Message is contained in a SOAP “envelope”.
Client sends message as text in an HTTP POST.
Web server passes message to SOAP server.
SOAP server invokes application, captures result.
Response returns via same route.
Notes:
The diagram illustrates how a SOAP message is sent from client to server application. Note that a SOAP server is required behind the web server to process the SOAP message and pass it to the appropriate application, as well as relay back the reply.
