			if(urlConnection instanceof HttpURLConnection){
			HttpURLConnection connection = (HttpURLConnection)urlConnection;
			BufferedReader bufIn = new BufferedReader(new InputStreamReader(connection.getInputStream()));
			String content = "";
			String line = "";
			while((line=bufIn.readLine())!=null)
