Rails - Feb 2009 - Maintaining session data across multiple domains

I''m working on an application that can be accessed from multiple
domains. I want to maintain session data across these domains, such
that if a user logs in at www.domain1.com, then moves to www.domain2.com,
they will still be logged in with the same account. Is this possible
in Rails? Could anyone point me towards a guide of how to achieve it?

Many thanks,
Adam

Well you will definitely need to move away from the cookie store.
I imagine you could do something like redirect users with no session  
to blah.domain.com - this creates/looks up their session id. Then it  
redirects them back to the original domain along with a token telling  
that app what the session id of the user should be (so that this app  
can set the cookie saying what the session id is)
