Action Controller Caching¶ ↑

Caching is a cheap way of speeding up slow applications by keeping the result of calculations, renderings, and database calls around for subsequent requests.

Note: To turn off all caching provided by Action Controller, set

config.action_controller.perform_caching = false

Caching stores¶ ↑

All the caching stores from ActiveSupport::Cache are available to be used as backends for Action Controller caching.

Configuration examples (FileStore is the default):

config.action_controller.cache_store = :memory_store
config.action_controller.cache_store = :file_store, '/path/to/cache/directory'
config.action_controller.cache_store = :mem_cache_store, 'localhost'
config.action_controller.cache_store = :mem_cache_store, Memcached::Rails.new('localhost:11211')
config.action_controller.cache_store = MyOwnStore.new('parameter')
