Well, the current popular way of having rails apps talk to each other is
to make them REST aware.
Rails 1.2 comes with a scaffold_resource generator that sets up the
controller for a domain object to be able to handle html requests or xml
REST requests. I don''t mean to make REST sound simple though...
there''s
plenty o'' learnin'' to do there.
If your sessions are stored in the db, then you could probably pass the
session id along with the REST request, although I''ve heard that future
versions of rails will favor writing the entire session into the
cookie... so that may not work with this approach.
But really, I''d question whether there''s some way you can get
away from
needing to use the session on the helper apps... it would probably be
simpler for the main app to ask a helper app to do some work on it''s
behalf without needing the session information at all.
Then again, if it''s just "helper function" sort of stuff that
the other
apps do for you, it might be better to look into backgrounddrb or a
message queue and make that side work asynchronous.
Hope this is helpful... and not just incoherent ramblings...
