API / $cache.has

Determines whether an item is present in the cache. NOTE: It is recommended that has() is only to be used for cache warming type purposes and not to be used within your live applications operations for get/set, as this method is subject to a race condition where your has() will return true and immediately after, another script can remove it making the state of your app out of date. MUST be thrown if the $key string is not a legal value.
