Questionaire 'bout cache_peer_access

# Promt reply is very very welcome q(^o^)p

Hello,there.

There is a question about the use of cache_peer_access.

[ GOAL ]
  When referring to some IP addresses group,
  set proxyB as proxy server for that access.

[ TRIAL ]
1. When I refer the URL contained within .dom1.tanaka.co.jp
   via proxyB instead of proxyA, it works well.
   (FIRST_UP PARENT is proxyB in access.log)

cache_peer_domain proxyA.tanaka.co.jp !.dom1.tanaka.co.jp
cache_peer_domain proxyB.tanaka.co.jp .dom1.tanaka.co.jp

2. In the analogy of above case, when I set up IPaddress
   instead of domainname, it doesn't woek well.

cache_peer_domain proxyA.tanaka.co.jp !192.138.22.0/25
cache_peer_domain proxyB.tanaka.co.jp 192.138.22.0/25

3. Even in the case of combining acl configuration and
   cache_peer_access instead, it resulted in failure.
   (At least it looks not well)

acl net5 dst 192.138.22.0/25
cache_peer_access proxyA.tanaka.co.jp deny net5
cache_peer_access proxyB.tanaka.co.jp allow net5

where http_access allow, icp_access allow, and
         miss_access allow is set to net5

Confirming access.log, although it shows
FIRST_UP PARENT is proxyB for 192.138.22.0/25 access,
but access.log contains hostname&domainname for that IP.
It looks result of success (i.e. reference for 192.138.22.0/25 via proxyB)
comes not due to squid.conf setup but via DNS solution
or the like.

Please write me soon and thank you so much for your cooperation !
Bye for now.
