related openser.cfg snippet:
if(t_check_status("302")){
                                xlog("$tU has a forward");
                                get_redirects("*", "redirected");
                                xlog("forwarding to $tU");
                                t_relay("5.6.7.8");
                                exit;
                        };

Any help is as always, greatly appreciated.
