求教httpClient的问题

最近开发一个项目，需要做一个爬虫，遇到了一下问题，访问google博客需要先登录https://www.blogger.com（注意这里是https协议），输入邮件和密码后进入博客首页http://www.blogger.com/home?pli=1(这里改成http协议了)。我用httpclient4模拟https登录过程，
开始创建https://www.google.com host对象
能成功返回以下结果：HTTP/1.1 200 OK
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"><html dir="ltr"><head><title>转接</title><meta http-equiv="refresh" content="0; url=http://www.blogger.com/home?pli=1"></head><body class="null lang_zh"><script type="text/javascript">    var expiry = new Date();    expiry.setTime(expiry.getTime() + 1000);    document.cookie="testCookie=true; expires=" + expiry.toGMTString();    if (document.cookie.indexOf("testCookie=") == -1) {      location.replace("/app/nocookies.html");    } else {      location.replace("http://www.blogger.com/home?pli\x3d1");    }  </script><script src="https://ssl.google-analytics.com/urchin.js" type="text/javascript">        </script><script type="text/javascript">          _uacct="UA-18003-7";          _uanchor=1;          _ufsc=false;          _usample = 10;          urchinTracker();          _uff=0;        </script></body></html>
以上是一个转接页面，目标是http://www.blogger.com/home?pli=1，这里改成http协议了，以后把host改成http://www.blogger.com对象，再用httpClient.execute(host,httppost);
返回以下错误:
