Httpclient4.3.1 关于禁止自动跳转

我想获得header中location的地址，禁止自动跳转的方式 我从网上看到的是httpClient.getParams().setParameter(ClientPNames.HANDLE_REDIRECTS,false);
但是看api文档，上面说getParams()
Deprecated.
(4.3) use RequestConfig.
怎么用requestconfig来禁止跳转，求指导

         HttpGet get = new HttpGet(url);
        RequestConfig requestConfig = RequestConfig.custom().setRedirectsEnabled(false).build();
        get.setConfig(requestConfig);

HttpGet httpGet = new HttpGet(url);
RequestConfig requestConfig = RequestConfig.custom().setRedirectsEnabled(false).build();
httpGet.setConfig(requestConfig);

post如何自动跳转呢
