Abstract

L'invention concerne un système de service Web dual et un procédé, selon lequel un serveur central de mise en mémoire tampon de données d'un serveur Web se substitue à un serveur Web qui ne peut pas fournir le service Web. Ce système comporte un client requérant qui transmet un nom de domaine d'un client du serveur Web à un serveur central en vue d'accéder à un site Web, qui reçoit les informations d'accès au réseau du moment provenant du serveur central, et qui accède au site Web au moyen des informations afin de recevoir le service Web. Ledit client du serveur Web sauvegarde périodiquement des données du site Web sur le serveur central et fournit le service Web par le biais du site Web et ledit serveur central permet de vérifier, en temps réel, si le client du serveur Web peut fournir le service Web, de mettre en tampon un site Web de sauvegarde reçu du client du serveur Web, et de transmettre des informations d'accès au réseau du site Web de sauvegarde, si le client du serveur Web ne fournit pas de service Web.
