Caching is implemented using memcached server. The application interacts with the memcached server using the Dalli client (https://github.com/mperham/dalli).
On staging and production environment, caching is enabled.
In case you need to use caching in the development environment as well, then make sure that in the config/environment/development.rb file,
config.action_controller.perform_caching = true
Also add the below two lines to development.rb
require 'active_support/cache/dalli_store23' config.cache_store = :dalli_store
To clear the cache, run script/console and run the following command
Rails.clear.cache
