如何从restlet/jetty响应中移除"Server“头部？

import org.restlet.Request;
import org.restlet.Response;
import org.restlet.routing.Filter;

public class ServerHeaderFilter extends Filter {

    @Override
    protected void afterHandle(Request request, Response response) {
        response.getHeaders().remove("Server");
    }
}

import org.restlet.Application;
import org.restlet.Restlet;
import org.restlet.routing.Router;

public class MyApplication extends Application {

    @Override
    public Restlet createInboundRoot() {
        Router router = new Router(getContext());
        router.attach("/resource", MyResource.class);

        // 添加自定义的ResponseFilter
        router.attach("/resource", ServerHeaderFilter.class);

        return router;
    }
}
