       HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
       connection.setDoOutput(true);
       connection.setRequestMethod("POST");
   
       request.write("login=ll&password=pp");
       request.flush();
       request.close();            
       String line = "";               
       InputStreamReader isr = new InputStreamReader(connection.getInputStream());
       //.... get string

You can read the location header to see where you've been redirected to

String header = connection.getHeaderField("location");

and then open a new connection to that URL.

You are most likely being redirected from HTTPS (login) to HTTP (post login). See this answer to another question for information on why HttpURLConnection is not automatically following the redirect in this case.
