Does not work on Rails 4

Could you please provide steps to reproduce? Tests that break would be even better. Thanks.

I'm not sure exactly what @sanjiv-hartleylab is seeing however I was having issues with Rails 4.2.7 loading a session created by this plug. I solved it by calling put_session(conn, "session_id", Base.encode16(:crypto.strong_rand_bytes(16), case: :lower)) to add a session id. It appears that without a session id Rails doesn't think a session exist when it tries to load it.

@paulnicholson where did you add the put_session call in your app?

@fbjork Well, my motivation for getting this to work was rails <-> elixir form posting with csrf validation. I wrote a plug to handle csrf protection in a rails compatible way and that plug ensures the session has a session id.
