Can I share a cookie between multiple domains pointing to the same Rails application?

Question

I have x.com pointing to apple.y.com , and separately, also one.y.com and two.y.com . I want a user who visits x.com, one.y.com or two.y.com to share the same sessions. Is it possible? If not, what is the best compromise?

Answer 1

one.y.comand two.y.comcan share cookies by setting cookies for the domain .y.com. This will transmit cookies in all subdomains y.com.
