Redis not working about flask-caching

[sh4nks]

It looks like it is using RedisCache from werkzeug directly instead of the 'wrapper' around RedisCache. Have you tried setting app.config['CACHE_TYPE'] to redis?

It was due to the package redis not being installed.

I don't know where I got the idea of using RedisCache directly from, but flask-caching could probably throw a better error than simply swallowing the ImportError in backends.py. I'm also not sure RedisCache should be exposed at all from the module?

backends.py lines 68-99

# RedisCache is supported since Werkzeug 0.7.
try:
    from werkzeug.contrib.cache import RedisCache 
    from redis import from_url as redis_from_url
except ImportError:
    pass 
else:
    def redis(app, config, args, kwargs):
        ...
        return RedisCache(*args, **kwargs)

Yeah I think it shouldn't be exposed. If you want you can open a new PR for this. Otherwise I'll try to find some time this evening :)

The suggested modification imports redis and RedisCache at the time of calling redis(), instead of at import time. I don't know if that causes any problems?
