module RocketIO

    # setup sessions.
    # there are 2 setups out of the box:
    #   - cookies
    #   - memcache
    # you can also use your own setup
    #
    # @note to disable sessions for some controller set sessions to nil or false
    #
    # @example keep sessions in cookies
    #   sessions :cookies
    #
    # @example keep sessions in cookies using custom options
    #   sessions :cookies, secret: 'someSecret', domain: 'some.domain'
    #
    # @example keep sessions in memcache
    #   sessions :memcache
    #
    # @example use a custom setup, i.e. github.com/migrs/rack-session-mongo
    #   $ gem install rack-session-mongo
    #
    #   require 'rack/session/mongo'
    #
    #   class Pages < RocketIO::Controller
    #     sessions Rack::Session::Mongo
    #   end

    # @example disable sessions for current controller
    #   sessions nil # or false
