RPC Architecture

The partner application access the servers of CARSiRENT through a URL (the location where the services resides) and CARSiRENT passed the request information to the handler.

The diagram on the right explains the XRS requests and response flow in detail. Please follow the architecture to get a clear picture of the communication.

In order to successfully make a request, the partner must open an HTTPS connection and transport an XML string with a POST method, read the reply and then close the connection.
The XML string is a part of an external message protocol defined by HTTP/1.0.
HTTP/1.0 is described in RFC 1945, HYPERTEXT TRANSFER PROTOCOL – HTTP/1.0.
