[squid-users] Forwarding loops...

Hi,

still using my 4 siblings in proxy-only.
Works fine for a while... until the digests are exchanged.
As expected, my logs are full of forwarding loops detected.

  2008/07/11 10:48:32| WARNING: Forwarding loop detected for:
  Client: 192.168.17.11 http_port: 192.168.17.11:8000
  GET http://192.168.16.23/img/taiwan.gif HTTP/1.0
  Pragma: no-cache
  User-Agent: Wget/1.10.2 (Red Hat modified)
  Accept: */*
  Host: 192.168.16.23

  X-Forwarded-For: 192.168.17.13, 192.168.17.11, 192.168.17.14
  Cache-Control: max-age=864000
  Proxy-Connection: keep-alive

The problem is, since the siblings are in 'proxy-only', they do not cache the looped objects and constantly asks their apache for it.
The next digests exchanges will fix the current loops, but will create new loops.
To solve this, I tried to prevent a squid from querying a sibling on behalf of another sibling:

  example of squid1.conf:
  cache_peer 192.168.17.12 sibling 8000 3130 proxy-only name=squid2
  cache_peer 192.168.17.13 sibling 8000 3130 proxy-only name=squid3
  cache_peer 192.168.17.14 sibling 8000 3130 proxy-only name=squid4
  
  acl from_squids src 192.168.17.12
  acl from_squids src 192.168.17.13
  acl from_squids src 192.168.17.14
  
  cache_peer_access squid2 deny from_squids
  cache_peer_access squid3 deny from_squids
  cache_peer_access squid4 deny from_squids

But it is not helping...
Any idea?

Thx,
JD
