Package com.nuecho.rivr.core.servlet.session Description

Session-related class used by HTTP servlet controller.

To overcome certain limitations and problems related to session tracking, Rivr implements its own session container and session tracking facility. Session ID is encoded as part of the path in the URI used by Rivr during turn execution. The Sessions are stored in the SessionContainer which is responsible for automatic session expiration. Note that once a dialogue is done, the associated session is removed automatically. The session container periodically check for dead session and collect them if necessary.
