This you need in case if storage node does not specify correct content

This prevents nginx from accumulating response in memory or writing ont
disk, thus saving resources which were already used on storage node.

It is possible to enable proxy_buffering and I don't know what impact on
performance it will have. And it is not possible to cache the URLs
returned by the tracker, but might be possible to cache the returned
entity itself.
