- # 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
