Abstract: A session context on a server can be shared between multiple, independent clients by employing many-to-one mapping of sessions to session context. Once a session context is established on the server, the originating client associated with that context can share the context with other clients. The server can provide the client with a certificate identifying the session context. The client, in turn, can pass the certificate to other clients. By initiating a server session with the certificate, the server assigns the pre-existing session context to a new session for a new client. A plurality of clients can thereby interact with a shared session context. This allows the clients to cooperate in a groupware fashion.
