Does it work also if you change that line to this instead:
[FONT="Courier New"]$request_type = ((isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) == 'on') || (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == '1') || (isset($_SERVER['HTTP_X_FORWARDED_BY']) && strstr(strtoupper($_SERVER['HTTP_X_FORWARDED_BY']),'SSL')) || (isset($_SERVER['HTTP_X_FORWARDED_HOST']) && (strstr(strtoupper($_SERVER['HTTP_X_FORWARDED_HOST']),'SSL') || strstr(strtoupper($_SERVER['HTTP_X_FORWARDED_HOST']),str_replace('https://', '', HTTPS_SERVER))) ) || || (isset($_SERVER['SCRIPT_URI']) && strtolower(substr($_SERVER['SCRIPT_URI'], 0, 6)) == 'https:') || (isset($_SERVER['SERVER_PORT']) && $_SERVER['SERVER_PORT'] == '443' ) ) ? 'SSL' : 'NONSSL';[/FONT]
