使用HttpConduit和HttpClientPolicy执行CXF配置的持久性

Question

我正在使用HttpConduit和HttpClientPolicy配置CXF。现在，每个请求都会看到以下自定义：

    Client client = ClientProxy.getClient(queryService);
    client.getRequestContext().put(Message.ENDPOINT_ADDRESS, server);
    HTTPConduit conduit = (HTTPConduit) client.getConduit();
    HTTPClientPolicy policy = new HTTPClientPolicy();
    policy.setConnectionTimeout(timeout * 1000);
    policy.setReceiveTimeout(timeout * 1000);

    if (AUTHENTICATION_TYPE_NTLM.equals(authenticationType))
        policy.setAllowChunking(false);

    if (authenticationCookie != null)
        policy.setCookie(authenticationCookie.toString());

    conduit.setClient(policy);

这些自定义是否可以在创建queryService实例时应用一次？如果是这种情况，我如何为每个请求单独设置身份验证cookie？
