So with multiple servers defined for an application under the
Multiserver, the session information can be cooperatively shared between
the servers?  I understand that the load balancing is done by the
director module, but is the session persistence also handled there or is
each App Server responsible for disseminating its current sessions to
the other servers?

Is this documented somewhere?  I am admittedly new to the Enhydra
paradigm and do not want to waste your time explaining something that
may have been documented elsewhere.  Perhaps I missed something?
