This is two different and separate things. One being Caching. The second
being fetching from an upstream peer (aka "parent").

To "serve cache" all you need is a cache in each proxy. If you mean
sharing cache, that is not possible in an up/down hierarchy relationship.

You can drop "hierarchy_stoplist".

Er, you can fit 3 of these 150M objects into your 500MB memory cache
space (cache_mem). If we assume your traffic is about average each one
of those will shove more than 10,000 small objects out to disk on
arrival, which could be very slow.
It would be a good idea to drop your in-memory object size limit to
permit more small objects to stay there.

There you go. You have enabled caching.

To fetch from an upstream proxy configure a link to it with cache_peer.
The relationship type you want is "parent".
