public interface SessionInitListener extends Serializable
Event listener that can be registered to a VaadinService to get an event when a new Vaadin service session is initialized for that service.

Because of the way different service instances share the same session, the listener is not necessarily notified immediately when the session is created but only when the first request for that session is handled by a specific service.
