It seems for some reason docker images are not cached:

Second attempt of a 'docker pull alpine' (after removing it with docker rm alpine):

Whats the best way to fix this?

edit: This project DOES seem to work with docker, but its not usable as a normal proxy. It would be awesome if you could intergrate their trick into your project: https://github.com/rpardini/docker-registry-proxy/tree/master
