Cachecade

A cache backend wrapper which lets you specify multiple cache backends in order of preference.

If one or more of your caching services are unavailable, this module will gracefully degrade to a lower priority cache service keeping your site running in case of a service failure.

This module is tested to work with the following cache backends, but should work with any module:

• Memcache
• Redis
• Drupal core database cache

Cache backends can be re-used multiple times for scenarios such as having both a local memcache service and a remote memcache fallback.
