If your seeking some mechanism to obtain a session by sessionID, then I would
think someone has had to implement this using their own method of tracking and
storing the sessionID (like I mentioned previously with a system that used
framesets...multiple sessions...and yes they stored and tracked their own
sessionID's). You may have to roll your own session cache and key on ID if your
interested in tracking http sessions.
I dont think shiro would go this far to implement multiple sessions. Its
possible but I haven't seen it.
I do think shiro would implement multiple Subjects. But that information could
be proprietary.
Sorry for my guesswork... but I hope it helps.
