    # we’re not going to use common sockets
    # but Unix sockets for faster communication
    upstream shop {
      # fail_timeout=0 means we always retry an upstream even if it failed
      # to return a good HTTP response (in case the Unicorn master nukes a
      # single worker for timing out).

      # for UNIX domain socket setups:
      server unix:/tmp/shop.socket fail_timeout=0;
