Remarques

Il WSHttpBindingBase fournit certaines fonctionnalités de base pour les liaisons utilisées pour configurer des services Web sécurisés, fiables et interopérables, tels que ceux implémentés par les WSHttpBinding contrats de service non duplex, et plus particulièrement pour les services sécurisés et interopérables WSFederationHttpBinding qui prennent en charge le protocole WS-Federation.

Par défaut, il génère une pile d’exécution qui utilise WS-Security pour la sécurité et l’authentification des messages, HTTP pour la remise des messages et un encodage de message Texte/XML. Il peut également être configuré pour utiliser WS-ReliableMessaging pour la fiabilité.

L’utilisation de WS-ReliableMessaging est configurable à l’aide du paramètre facultatif reliableSessionEnabled .
