In Rails 1.2 the default session store is file based. This is inefficient and difficult to maintain. In Rails 2.0 the default is now cookie based which has several benefits as you will see in this episode.
in environment.rb
Rails::Initializer.run do |config|
config.action_controller.session = {
:session_key => '_store_session',
:secret => '851939c37d94574e284ded8437d4ea3447dae24cc5bda61d8eaf2731d49273bc4c620'
}
end
