Cache Not Found Keys

It is now possible (v.1.0.9) to cache not found keys in upper level adapters of the adapter stack. The configuration option cache_not_found_keys can be set at the adapter level.

Note that this option, obviously, does not apply to the last level of the cache hierarchy.

Usage

Note that must provide an adapter name and an array of options. Each adapter has different configuration options.

To start setting data:
