-    # 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 with 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
