Service Oriented Access Protocol

Steps to making a SOAP request:

• Identify the method (POST) and the target (/soap)
• content-type identifies that the message is XML (text/xml; charset=UTF-8

)
• The remainder of the XML document has three parts:
• Envelope is the container of the SOAP message and body.  It also identifies the namespaces, which may include:
• xmlns:soap SOAP envelope namespace
• xmlns:xsi XML Schema for instances
• xmlns:xsd XML Schema for data types
• xmlns:soapenc SOAP encoding namespace 
• Header is optional.  Must be first item in Envelope if present.
• Body makes up the bulk of the message.  It contains method name and arguments for an RPC call.
• On the server, a process accepts the SOAP message.  When it recognizes that it is a SOAP request, it forwards the message to the SOAP engine.
• What type of process might perform this operation?
• The SOAP handler is then responsible for processing the message and taking necessary action.
