- Using Rails 4.1.8
- People can have a custom domain to use with our app
- For some actions, we use ssl and redirect them to the domain we provide them
- If the person has a custom domain, I want as much of their time using the app to be on that domain
- I need a way to carry sessions/cookies over to another domain
- This, for example, will allow them to use ssl to sign in on our domain and I can redirect them back to their custom domain, signed in there
