I’m working on an application that can be accessed from multiple

in Rails? Could anyone point me towards a guide of how to achieve it?
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)
