L'invention concerne un procédé de gestion de cache consistant à : résoudre une demande de requête d'informations reçue pour obtenir un identifiant de requête présent dans la demande de requête d'informations ; chercher dans un cache pour déterminer si l'identifiant de requête existe ; dans le cas où l'identifiant de requête n'existe pas dans le cache, exécuter la demande de requête d'informations pour rechercher les informations correspondantes dans une base de données ; et dans le cas où une période de temps durant laquelle la demande de requête d'informations est exécutée dépasse un seuil de période de temps prédéfini, effectuer une mise en cache correspondante de la demande de requête d'informations comprenant l'identifiant de demande et les informations recherchées, et renvoyer les informations recherchées.
