android HTTP post方法时，如何使用cookies

      HttpURLConnection conn = (HttpURLConnection) url.openConnection();             //set cookie. sCookie is my static cookie string       if(sCookie!=null && sCookie.length()>0){         conn.setRequestProperty("Cookie", sCookie);                }       // Send data       OutputStream os = conn.getOutputStream();       os.write(mData.getBytes());       os.flush();       os.close();       // Get the response!       int httpResponseCode = conn.getResponseCode();           if (httpResponseCode != HttpURLConnection.HTTP_OK){        throw new Exception("HTTP response code: "+httpResponseCode);       }       // Get the data and pass them to the XML parser       InputStream inputStream = conn.getInputStream();               Xml.parse(inputStream, Xml.Encoding.UTF_8, mSaxHandler);               inputStream.close();       //Get the cookie       String cookie = conn.getHeaderField("set-cookie");       if(cookie!=null && cookie.length()>0){         sCookie = cookie;              }       /*  many cookies handling:                String responseHeaderName = null;       for (int i=1; (responseHeaderName = conn.getHeaderFieldKey(i))!=null; i++) {         if (responseHeaderName.equals("Set-Cookie")) {                  String cookie = conn.getHeaderField(i);          }       }*/               conn.disconnect();
