      # 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 #find_session, #write_session and
      # #delete_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#set_cookie
      # * :skip will not a set a cookie in the response nor update the session state
      # * :defer will not set a cookie in the response but still update the session
      #   state if it is used with a backend
      # * :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
      # <tt>env['rack.session.options']</tt>. 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.
      #
      # Is Rack::Utils::Context compatible.
      #
      # Not included by default; you must require 'rack/session/abstract/id'
      # to use.
