As mentioned earlier, when an HTTP session is created in GlassFish,
only the HttpSessionListener residing on the instance where the
session was created will be notified.
However, this HttpSessionListener could in turn notify all other
instances in the cluster about the session creation, by sending a
corresponding GMS message to them. The same would happen for
sessionDestroyed events.
I'm not sure if this fully answers your question, though.
