How to get correct html base url after forward?

Hello guys!

I'm playing around with some code that reads content from a URL like:

        URL nu;
        try {
           
            nu = new URL("http://www.nu/");
            BufferedReader in = new BufferedReader(
                    new InputStreamReader(nu.openStream()));

                    String inputLine;
                    while ((inputLine = in.readLine()) != null)
                        System.out.println(inputLine);
                    in.close();
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

How ever I would like to detect the html base URL for the response.

If you go to http://www.nu/ in a browser you will see that there is a "forward" to the correct URL http://www.nunames.nu/

Is there a way to find out the "new" URL for the response?

I have tried like:

            System.out.println(nu.getHost());
            System.out.println(nu.getPath());
            System.out.println(nu.toURI().getHost());
            System.out.println(nu.toURI().getPath());

Best regards
