Most of the time, you'll simply use the default request type included with
Zend_XmlRpc_Server,
Zend_XmlRpc_Request_Http. However, there may be times when you
need XML-RPC to be available via the CLI, a
GUI, or other environment, or want to log incoming requests. To do
so, you may create a custom request object that extends
Zend_XmlRpc_Request. The most important thing to remember is to
ensure that the getMethod() and
getParams() methods are implemented so that the
XML-RPC server can retrieve that information in order to dispatch the
request.
