[squid-users] Forcing squid to use parent always

I have one cache on a local LAN and another cache on the LAN that
this LAN is dialed up to. I want to force the local cache to always
use the cache on the other LAN (traffic to the internet goes through
that LAN anyway). So I have this configured in the local cache:
[where XXX.XXX.XXX.XXX is the IP address of the parent cache]

cache_peer XXX.XXX.XXX.XXX parent 800 0 default no-query

which is the best I could figure out from the documentation.
I want to use HTTP rather than ICP between caches for reasons
that involve future network topology plans.

Most requests go to the parent. However, I occaisionally get a
request going direct. How can I force this to go to the parent?
In the near future, the local cache won't even have direct access
and I want to figure out how to solve this before then.

Here is the complete config of the local cache:
[where XXX.XXX.XXX.XXX is the IP address of the parent cache
and YYY.YYY.YYY.YYY is the network address of the local LAN]

cache_peer XXX.XXX.XXX.XXX parent 800 0 default no-query
