Remarques

La IssueDate propriété représente la date et l’heure locales auxquelles le ticket d’authentification par formulaire a été émis. La RenewTicketIfOld méthode utilise la valeur de propriété IssueDate pour déterminer si la date et l’heure Expiration d’un ticket d’authentification par formulaire doivent être renouvelées et utilise également la valeur de propriété IssueDate pour déterminer la nouvelle Expiration date et l’heure. Lorsqu’un ticket est renouvelé, la IssueDate propriété est mise à jour avec la date et l’heure locales.
