Form login with java, then change URL

Question

this is my problem, theres a site where I need to login with a login + pass. now when I try to take a new url (on the same host) I'm back at the login page, so basically I want to login, and then keep that login to parse several pages on the server... I didn't write this code myself, but it works for the login :p now I just need to change the url in the same connection I guess
String argus[]= {url,"name",name,"password",password};
          URL u = new URL(argus[0]);
          String postdata = URLEncoder.encode(argus[1]) + "=" + URLEncoder.encode(argus[2]);
          for (int i=3;i+1<argus.length;i+=2) {
          postdata = postdata + "&" + URLEncoder.encode(argus) + "=" + URLEncoder.encode(argus[i+1]);
          URLConnection uc = u.openConnection();
          uc.setDoOutput(true);
          OutputStreamWriter out =
          new OutputStreamWriter(uc.getOutputStream(),"ASCII");
          out.write(postdata);
          out.close();
     String s;
          while ((s = r.readLine()) != null) {
          System.out.println(s);
so far it works perfectly, but now I need to get another html page on that server, but when I create a new URL it goes back to the login page...
any ideas ?

The page probably sets a cookie. This article tells about one way to handle cookies:
