# 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
