[squid-users] parents and siblings in a complex enviroment

I have 4 caches. 2 caches at the HQ and 2 caches at a branch office.
Here's the peer info for each of the caches.

hq-1:
cache_peer hq-2 sibling 3128 3130

hq-2:
cache_peer hq-1 sibling 3128 3130

branch-1:
cache_peer hq-1 parent 3128 3130
cache_peer hq-2 parent 3128 3130
cache_peer branch-2 sibling 3128 3130

branch-2:
cache_peer hq-1 parent 3128 3130
cache_peer hq-2 parent 3128 3130
cache_peer branch-1 sibling 3128 3130

The two HQ caches are siblings, the two caches at the BRANCH are
siblings and use the two caches at HQ as parents.

When a request comes into a BRANCH cache, the cache queries it's sibling
and both parents at HQ. Do the parents then query each other (since
they are siblings)? If so, does anyone have ideas on the best way to
prevent these duplicate queries?

Thanks in advance,

--Eric
