Session cookies, the Rails-2 kind, are transient because that's safer. In some applications safety isn't important. The following makes the session cookies persist for a year.
class ApplicationController < ActionController::Base before_filter :update_session_expiration_date private def update_session_expiration_date unless ActionController::Base.session_options[:session_expires] ActionController::Base.session_options[:session_expires] = 1.year.from_now end end end
