Sharing services w/ middleware

[markalanevans]

Goliath + RackAttack + Redis

I'd like to be able to pass the redis connection i create in the config dir to the rack middleware i created:

config['redis'] = EM::Synchrony::ConnectionPool.new size: 2 do
  Redis.new(:host => redis_host, :port => redis_port, :password => redis_password)
end

And use redis the same redis connection for my middleware.

Rack::Attack.cache.store = Rack::Attack::StoreProxy::RedisStoreProxy.new(redis)

Problem being that in middleware redis is not defined.

How might i share this connection?
