set_default_handler(&handler)
[permalink][rdoc]Sets handler as the default-handler, which is called when no handler for a method-name is found. handler is a code-block. The default-handler is called with the (XML-RPC) method-name as first argument, and the other arguments are the parameters given by the client-call.
If no block is specified the default of XMLRPC::BasicServer is used, which raises a XMLRPC::FaultException saying "method missing".
