-      # ID sets up a basic framework for implementing an id based sessioning
-      # service. Cookies sent to the client for maintaining sessions will only
-      # contain an id reference. Only #get_session and #set_session are
-      # required to be overwritten.
-      #
-      # All parameters are optional.
-      # * :key determines the name of the cookie, by default it is
-      #   'rack.session'
-      # * :path, :domain, :expire_after, :secure, and :httponly set the related
-      #   cookie options as by Rack::Response#add_cookie
-      # * :defer will not set a cookie in the response.
-      # * :renew (implementation dependent) will prompt the generation of a new
-      #   session id, and migration of data to be referenced at the new id. If
-      #   :defer is set, it will be overridden and the cookie will be set.
-      # * :sidbits sets the number of bits in length that a generated session
-      #   id will be.
-      #
-      # These options can be set on a per request basis, at the location of
-      # env['rack.session.options']. Additionally the id of the session can be
-      # found within the options hash at the key :id. It is highly not
-      # recommended to change its value.
