Overview

creating a new cache handler is as simple as extending from the handler class, setting the class to use as the cache by calling cache_class(“Redis”) and then implementing the increment and get methods for that cache type.

If you don’t want to extend from Handler you can just create a class that implements increment(key), get(key) and handles?(info)

you can then initialize the middleware and pass :cache=>CACHE_NAME as an option.
