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
