hi, i''m wondering if anyone knows a simple way to grab all the active
session
objects in a system. i''m adding a messaging component to our app and i
want to
enable users who are online to see when they''ve been messaged --
messages are
associated with users, so basically what i want to do is go through the
sessions, find the one for a specific user, and reload it when they''ve
received
a message.
i''m using rails'' default filesystem-based sessions. i found
this post that
describes something similar, but it requires changing to db-stored sessions,
which i''d rather not do:

aren''t sessions held in memory somewhere? is there any simple way to
just get
them from memeory, rather than the filesystem or db?
