public ServerBuilder accessLogger(Logger logger) {
        requireNonNull(logger, "logger");

    }
Sets the default access {@link Logger} for all {@link VirtualHost}s.
The {@link VirtualHost}s which do not have an access logger specified by a {@link VirtualHostBuilder}
will have the same access {@link Logger} when {@link ServerBuilder#build()} is called.
