Device(?) works strange

Rails
1
  1. I build http://SOME.example.com and http://OTHER.example.com on the
    server SOME.example.com.
    useing nginx unicorn RoR Device
  2. For the clone, http://SOME_CLONE.example.com and
    http://OTHER_CLONE.example.com are builed on the server
    SOME_CLONE.example.com
  3. Only SOME.example.com is defined on DNS, others are on the /etc/hosts

3 of 4 domains work well, but SOME_CLONE works strange

  1. when access ‘needs authenticate page’ , redirected to
    SOME/users/sign-in, not to SOME_CLONE/users/sign-in

  2. Explicitly access to SOME_CLONE/users/sign-in, can access to
    SOME_CLONE
    and later accesses reach to SOME_CLONE

  3. when access SOME_CLONE/foo, access_log s are
    SOME_CLONE/Rails.root/log/product " Started GET “/foo” " and
    "Completed
    401 Unauthorized "
    SOME_CLONE/access/log /foo(status is 302)
    SOME_/access/log /users/sign-in

how can i resolve

Thanks
