Yes, otherwise they won't share the cache :)

I also recommend you turning on cache digests on all proxies.

No, I don't recommend you doing that. allowing misses meane allowing
fetching of files that are not in cache directory, which is used for child
proxies - siblings should be only allowed to fetch content that is already
in cache.

> miss_access allow proxy1.example.com

However you should allow fetching misses to your clients/users. Otherwise
they won't be allowed to access pages that are not already in cache(s).
