RPC - Remote Procedure Call

The general model is very simple and patterned after human conversation habits. The following illustrations show the simplicity of the general concept.

On the programming level, HXP uses RPC (Remote Procedure Calling protocol) that works over the Internet, Intranet and local host.

An RPC message is an HTTP request. The body of the request is in XML. A procedure executes on the server and the value it returns is also formatted in XML.

Procedure parameters can be scalars, numbers, strings, dates, etc.; and can also be complex record and list structures.
