https http trick php - need to use request_type

hi i have a piece of code case 'url': if (isset($HTTP_GET_VARS['goto']) && tep_not_null($HTTP_GET_VARS['goto'])) { $check_query = tep_db_query("select takeaways_url from " . TABLE_TAKEAWAYS_DESCRIPTION . " where takeaways_url = '" . tep_db_input(urldecode($HTTP_GET_VARS['goto'])) . "' limit 1"); if (tep_db_num_rows($check_query)) { tep_redirect('https://' . urldecode($HTTP_GET_VARS['goto'])); } } break; but i dont want to force use https:// in the line tep_redirect('https://' . urldecode($HTTP_GET_VARS['goto'])); id like to use $request_type = (getenv('HTTPS') == 'on') ? 'SSL' : 'NONSSL'; or something so that it only attempts to load a https url if HTTPS is enabled on the server the way the code works is if i use tep_redirect('http://' . urldecode($HTTP_GET_VARS['goto'])); then it always goes to a http link (non secure) and if i use tep_redirect('https://' . urldecode($HTTP_GET_VARS['goto'])); it always will go to a https link (secure) but i dont want it this way i want it to go to the connection type which is returned by the following rule $request_type = (getenv('HTTPS') == 'on') ? 'SSL' : 'NONSSL'; this way if i disable https or my certificate runs out then it will automatically go to the http version. CODE I TRIED WAS --------------------------- $request_type = (getenv('HTTPS') == 'on') ? 'https://' : 'http://'; case 'url': if (isset($HTTP_GET_VARS['goto']) && tep_not_null($HTTP_GET_VARS['goto'])) { $check_query = tep_db_query("select takeaways_url from " . TABLE_TAKEAWAYS_DESCRIPTION . " where takeaways_url = '" . tep_db_input(urldecode($HTTP_GET_VARS['goto'])) . "' limit 1"); if (tep_db_num_rows($check_query)) { tep_redirect('$request_type' . urldecode($HTTP_GET_VARS['goto'])); } } break; ----------------------------------------------- it threw up a comp[ete mess of a url NON SECURE and even request_type returned NONSSL even though my server is HTTPS please help
