initCookie perUser semantics

[Subbu Allamaraju <subbu@bea.com>]

Could someone clarify if the initCookie operation should be called once 
per user's session for each portlet on a producer, or once for all 
portlets on a producer?

 From earlier discussions, I vaguely recall that perUser implies that 
the initCookie should be called once per portlet per user's session on 
the consumer.

Thanks
