    # Rack::Session::Pool provides simple cookie based session management.
    # Session data is stored in a hash held by @pool.
    # In the context of a multithreaded environment, sessions being
    # committed to the pool is done in a merging manner.
    #
    # The :drop option is available in rack.session.options if you wish to
    # explicitly remove the session from the session cache.
    #
    # Example:
    #   myapp = MyRackApp.new
    #   sessioned = Rack::Session::Pool.new(myapp,
    #     :domain => 'foo.com',
    #     :expire_after => 2592000
    #   )
    #   Rack::Handler::WEBrick.run sessioned
