    System.out.println("qui");

    RequestDispatcher d;
    UtenteDAO ud = new UtenteDAO();

You can set the response of your servlet to status code 301. Something like below.

response.sendRedirect("https://www.google.com");

This will instruct the browser to go to www.google.com, you can replace this with your URL.
