Description copied from interface: TicketCache

Adds a new Ticket to the cache, returning a String identifier that uniquely matches the registered Ticket. This String identifier need not be globally unique, but two properties must be guaranteed: - The ticket cache must associate the identifier with the Ticket for the lifetime of the ticket. - The ticket cache must ensure that once a ticket expires, its identifier does not return a valid ticket.
