# one of :active_record_store, :drb_store,
# :mem_cache_store, or :memory_store or your own class
ActionController::Base.session_options[:session_key] = 'my_app'
# use an application specific session_key
ActionController::Base.session_options[:session_id] = '12345'
# use this session_id. Will be created if not specified
ActionController::Base.session_options[:session_expires] = 3.minute.from_now
# how long before a session expires?
ActionController::Base.session_options[:new_session] = true
# force the creation of a new session
ActionController::Base.session_options[:session_secure] = true
# only use sessions over HTTPS
ActionController::Base.session_options[:session_domain] = 'invisible.ch'
# Specify which domain this session is valid for (default: hostname of server)
ActionController::Base.session_options[:session_path] = '/my_app'
