This is a pluggable backend for Cacher (https://github.com/addisonj/node-cacher)

A small adapter that uses redis as a backend

CacherRedis takes the same parameters as node-redis.createClient (https://github.com/mranney/node_redis)

var CacherRedis = require('cacher-redis')
var cacheBackend = new CacherRedis(port, host, opts)

Additionally, it can take an existing redis connection and resuse it:

var redisClient = require('redis').createClient()
var CacherRedis = require('cacher-redis')
var Cacher = requrie('cacher')
var cacher = new Cacher(new CacherRedis(redisClient))

Keys are also namespaced, opts.namespace defines the namespace, the deafult namespace is "cacher"
