Manually cache the content in the key determined by path. Example:

  cache_page "I'm the cached content", "/lists/show"

    # File vendor/rails/actionpack/lib/action_controller/caching.rb, line 84
84:         def cache_page(content, path)
85:           return unless perform_caching
86: 
87:           benchmark "Cached page: #{page_cache_file(path)}" do
88:             FileUtils.makedirs(File.dirname(page_cache_path(path)))
89:             File.open(page_cache_path(path), "wb+") { |f| f.write(content) }
90:           end
91:         end

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.

 95:         def caches_page(*actions)
 96:           return unless perform_caching
 97:           actions.each do |action|
 98:             class_eval "after_filter { |c| c.cache_page if c.action_name == '#{action}' }"
 99:           end
100:         end

Expires the page that was cached with the path as a key. Example:

  expire_page "/lists/show"

74:         def expire_page(path)
75:           return unless perform_caching
76: 
77:           benchmark "Expired page: #{page_cache_file(path)}" do
78:             File.delete(page_cache_path(path)) if File.exists?(page_cache_path(path))
79:           end
80:         end
