HttpURLConnection's setFollowRedirects(false) doesnt work for the instance on which its been called. Even though we set this to false , it does redirects automatically.

How to reproduce it:
====================
Take the following test client and servlet

import java.net.*;
import java.io.*;

public class RedirectTestClient {


        public static void main(String[] args) {

                HttpURLConnection ucon = null;
                int responseCode;

                try {
                                URL url = new URL("http://javacup.sfbay.sun.com:8080/examples/servlet/HttpRedirect");
                                
                                System.out.println("Before opening url connection ");
                                ucon = (HttpURLConnection) url.openConnection();
                                ucon.setFollowRedirects(false);
    
                                System.out.println("Before connect ");
                                ucon.connect();
                                System.out.println("After connect ");
                                System.out.println(" Get follow redirects " + ucon.getFollowRedirects());
                                

                                System.out.println(" Before getting response code ");
                                try {
                                        System.out.println(" Response code " + ucon.getResponseCode());
                                } catch(ProtocolException pexp) { pexp.printStackTrace(); }

                                System.out.println(" After getting response code ");
                                ucon.disconnect();
                                System.out.println("After disconnect ");

                                ucon = (HttpURLConnection) url.openConnection();
                                System.out.println("Before connect ");
                                ucon.connect();
                                System.out.println("After connect ");
                                System.out.println(" Get follow redirects " + ucon.getFollowRedirects());
                                System.out.println(" Before getting response code ");
                                System.out.println(" Response code " + ucon.getResponseCode());
                                System.out.println(" After getting response code ");

                }catch(Exception exp) {
                        exp.printStackTrace();
                }

        } // End of method

} // End of class

Servlet class:
---------------

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class HttpRedirect extends HttpServlet {

    public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException
    {
        try {
                System.out.println("In HttpRedirect servlets do get");

                response.setContentType("text/html");
                response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY);

                System.out.println("In HttpRedirect servlets before redirect ");
                response.sendRedirect("http://javacup.sfbay.sun.com:8080/examples/servlet/HttpRedirect");
                

        } catch(Exception exp) {
                exp.printStackTrace();
        }

   } // End of doGet
}
