The SOAP protocol, also called simple object access protocol, is used to exchange information during the implementation of Web services on a computer network. The extensible Markup Language (XML), which is dependent on message format, also relies upon other application layer protocols in remote Procedure Call (RFC), and hypertext Transfer Protocol for message negotiation and transmission. SOAP is used to create a layer of web services protocol stack that provides a message frame for Cheap Hosting web services. XML-based protocols consist of three parts. They are an envelope-described message and its processing. Only web service-enabled web sites can receive the SOAP message.
Cheap web hosts will return an XML document with data. SOAP architecture is made up of several layers such as message format, message exchange patterns and underlying transport protocol bindings. It also includes a message processing model, protocol extensibility, protocol extensibility, and message processing model. XML-PRC is able to access simple object access protocols because it borrows them from interaction and transport.
Specification: A process model is a set or rules that are used to process the SOAP message. An extensibility module, the object access protocol, defines the concept SOAP features and simple object access protocol models.
The SOAP underlying the protocol-binding framework defines the rules to allow SOAP nodes to exchange SOAP messages. The structure of SOAP messages is defined by the object access protocol message construct. The distribution of messages is handled by the objects Access protocol processing model
These SOAP nodes can be used as SOAP sender, SOAP recipient, and SOAP message path initial. Simple object access protocol that uses internet application layer pro SMPT or Hypertext Transfer Protocol are valid application layer protocols used as transport for SOAP. XML is a standard message format such as CORBA,GIOP and DCOM. Hardware appliances can be used to speed up the processing of XML message.
Binary XML messages are streamlining by removing the XML requirement. SOAP is used to permit different transport protocols. SOAP model tunnel, such as Hypertext Transfer Protocol, allows for the easy passing of firewalls and cheap proxy without notifying the SOAP protocol.
