Implements a CGI-based XML-RPC server.
((<XMLRPC::BasicServer>))
— XMLRPC::CGIServer.new( *a )
Creates a new (({XMLRPC::CGIServer})) instance. All parameters given are by-passed to ((<XMLRPC::BasicServer.new>)). You can only create ((*one*)) (({XMLRPC::CGIServer})) instance, because more than one makes no sense.
Call this after you have added all you handlers to the server. This method processes a XML-RPC methodCall and sends the answer back to the client. Make sure that you don't write to standard-output in a handler, or in any other part of your program, this would case a CGI-based server to fail!
