Overview

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

You can read more about each approach by clicking the modules below.

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')
