can Sessions scope cross multi-apps? single sign-on?

bump - still interested any anyone knows the answer to this one?

Do your apps share the same database? If so, then it sounds pretty easy. You’d want to make sure that your cookie scope is set to use the entire domain rather than just the host (
instead of, and the cookie can be used on any app within that domain scope.

Just throwing this out. I think it could work.

Tks Michael - would this be a manual activity I’d have to do (i.e. this wouldn’t work by default?). I could use the rails cookie mechanisms then I guess?

From what I can recall, the cookie is set to a host specifc scope instead of the entire domain. So yeah, you’d have to alter it.
