∟XML-RPC - Remote Procedure Call with XML and HTTP

∟What Is XML-RPC?

This section describes what is XML-RPC - a specification on how to make a Remote Procedure call (RPC) by passing XML messages using HTTP requests and responses over the Internet.

Here is the definition of XML-RPC from the XML-RPC home page at http://www.xmlrpc.com:

"It's a spec and a set of implementations that allow software running on disparate operating systems, running in different environments to make procedure calls over the Internet."

"It's remote procedure calling using HTTP as the transport and XML as the encoding. XML-RPC is designed to be as simple as possible, while allowing complex data structures to be transmitted, processed and returned."

My understanding of XML-RPC is that it is specification of how to:

• Define a remote method call in XML.
• Send a remote method call over Internet as a HTTP request.
• Define returning values of a remote method call in XML.
• Receive returning values of a remote method call as a HTTP response.

RPC stands for Remote Procedure Call.
