### Avant et après la `response` { #before-and-after-the-response }

Vous pouvez ajouter du code à exécuter avec la `request`, avant que tout *chemin d'accès* ne la reçoive.

Et aussi après que la `response` a été générée, avant de la renvoyer.

            if (LogStream.level > 0) {
                ex.printStackTrace(log);
            }
            return null;
        }
