CA 2533773

Techniques allow a client to be switched from a session on a server to another session on another server in a way that is a transparent to the application for which the initial session was established. Thus, under transparent session migration, a client is switched between sessions without executing application instructions tailored to accomplish the migration. Instead, a client-side interface component, through which the application interacts with the server, handles details of migration, modifying the internal state of the client-side interface component to effect the same. Legacy applications do not have to be modified in order to institute techniques described herein.

La présente invention a trait à des techniques permettant la passage par un client d'une session sur un serveur à une autre session sur un autre serveur d'une manière transparente à l'application pour laquelle la session initiale a été établie. Ainsi, sous une migration de session transparente, le client passe d'une session à une autre sans exécution d'instructions d'applications individualisées pour réaliser la migration. Au lieu d'une telle exécution, un composant d'interface côté client, à travers lequel l'application se trouve en interaction avec le serveur, gère les détails de migration, en modifiant l'état interne du composant d'interface côté client pour réaliser ladite migration. Des applications partagées ne nécessitent pas de modification en vue de l'établissement des techniques de l'invention.
