Expires and ETag based caching is enabled by default, but with a simple line in the application.rb/production.rb you can disable it:
Flexirest::Base.perform_caching = false
or you can disable it per classes with:
class Person < Flexirest::Base
perform_caching false
end
If Rails is defined, it will default to using Rails.cache as the cache store, if not, you'll need to configure one with a ActiveSupport::Cache::Store
compatible object using:
Flexirest::Base.cache_store = Redis::Store.new("redis://localhost:6379/0/cache")
