title: How split iframe and non-iframe sessions in Rails?
body: <p>I have rails application on my website (A*) and application on different resource (B*) based on iframe of application A*.
  When I logged in from iframe app B* then rails store my session in cookies and rewrite old session started from pure application A* (if it is).
