  controller.cookies
end

#last_request_update_allowed? ⇒ Boolean

You can disable the updating of ‘last_request_at` on a per-controller basis.

# in your controller
def last_request_update_allowed?
  false
end

For example, what if you had a javascript function that polled the server updating how much time is left in their session before it times out. Obviously you would want to ignore this request, because then the user would never time out. So you can do something like this in your controller:

def last_request_update_allowed?
  action_name != "update_session_time_left"
end

See ‘authlogic/session/magic_columns.rb` to learn more about the `last_request_at` column itself.

Returns:

  • (Boolean)

#renew_session_id ⇒ Object

Inform Rack that we would like a new session ID to be assigned. Changes the ID, but not the contents of the session.

The ‘:renew` option is read by `rack/session/abstract/id.rb`.

This is how Devise (via warden) implements defense against Session Fixation. Our implementation is copied directly from the warden gem (set_user in warden/proxy.rb)
