Page Caching
Since Rails 4 Page Caching has been extracted to the actionpack-page_caching.
In config/application.rb:
config.action_controller.page_cache_directory = "#{Rails.root.to_s}/public/deploy"
Page caching is enabled per-action by using caches_page method.
class PagesController < ApplicationController
caches_page :index
end
