Check if this helps

public class GetHttpHeaders {
        public static void main(String[] args) throws IOException {
            try {
                URL url = new URL("http://localhost:8080");
                URLConnection conn = url.openConnection();

                for (int i = 0;; i++) {
                    String name = conn.getHeaderFieldKey(i);
                    String value = conn.getHeaderField(i);
                    if (name == null && value == null) {
                        break;
                    }
                    if (name == null) {
                        System.out
                                .println("Server HTTP version, Response code:");
                        System.out.println(value);
                        System.out.print("\n");
                    } else {
                        System.out.println(name + "=" + value);
                    }
                }
            } catch (Exception e) {
            }
        }
    }

Try the blow link. There is a tool in eclipse name TCP/IP monitor .It provides a console. All you have to add is you server port lets assume localhost:8080 and a monitoring port 8081 (according to reference )

then when you will call on http://localhost:8081/your_servlet_or_page/... the call will be redirect to http://localhost:8080/your_servlet_or_page/... and you will be able to see headers in console TCP/IP monitor console

reference # http://www.avajava.com/tutorials/lessons/how-do-i-monitor-http-communication-in-eclipse.html http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.wst.wsi.ui.doc.user%2Ftasks%2Ftmonitor.html

The above reference is tested by me..it is working fine.
