protocol as the delivery mechanism. Later, with the introduction of new features, this standard slowly evolved into today's SOAP protocol. The XML-RPC agreement is a registered patent project. The XML-RPC sends an HTTP request to the server that installed the protocol. The client that makes the request is generally the software that needs to be called to the remote system.
