code: func (server *Server) HandleHTTP(rpcPath, debugPath string) {
  	http.Handle(rpcPath, server)
  	http.Handle(debugPath, debugHTTP{server})
  }
docs: // HandleHTTP registers an HTTP handler for RPC messages on rpcPath,
  // and a debugging handler on debugPath.
  // It is still necessary to invoke http.Serve(), typically in a go statement.
