                        function cdn_output($result) {
                            $cdn_domain = '';
                            $http_scheme = (isset($_SERVER['HTTPS']) && (($_SERVER['HTTPS'] == 'on') || ($_SERVER['HTTPS'] == '1'))) ? 'https' : 'http';
                            $cdn_domain = $http_scheme .'://'. $cdn_domain;
                            $result = str_replace($http_scheme . "://" . $_SERVER['HTTP_HOST'] . '/image/', $cdn_domain . '/image/', $result);
                            $result = str_replace('src="catalog/view/javascript/', 'src="' . $cdn_domain . '/catalog/view/javascript/', $result);
                            $result = str_replace('href="catalog/view/javascript/', 'href="' . $cdn_domain . '/catalog/view/javascript/', $result);
                            $result = str_replace('src="' . $http_scheme . "://" . $_SERVER['HTTP_HOST'] . '/catalog/view/javascript/', 'src="' . $cdn_domain . '/catalog/view/javascript/', $result);
                            $result = str_replace('src="catalog/view/theme/journal2/image/', 'src="' . $cdn_domain . '/catalog/view/theme/journal2/image/', $result);
                            $result = str_replace('src="catalog/view/theme/default/image/', 'src="' . $cdn_domain . '/catalog/view/theme/default/image/', $result);
                            $result = str_replace('href="catalog/view/theme/journal2/stylesheet/', 'href="' . $cdn_domain . '/catalog/view/theme/journal2/stylesheet/', $result);
                            $result = str_replace('href="catalog/view/theme/default/stylesheet/', 'href="' . $cdn_domain . '/catalog/view/theme/default/stylesheet/', $result);
