caches_page(*actions)

Caches the actions using the page-caching approach that‘ll store the cache in a path within the page_cache_directory that matches the triggering url.

Usage: 

  # cache the index action
  caches_page :index

  # cache the index action except for JSON requests
  caches_page :index, :if => Proc.new { |c| !c.request.format.json? }
