Hello, I was trying to use multicast when I first run into this problem... so i moved to unicast to make solve the issue first... it turns our in unicast the problem was simple the http port number in the cache-peer param was wrong. SQUID was indeed trying to connect to the peers but fails and only then does it connect to the origin server. I had to use debug All,9 to see this mistake! Now I switched back to multicast and the problem is indeed still there. in the full debug mode I see the peer requets sent and then immidiately the DIRECT path is used... later the UDP_HIT arrives, but too late! icpHandleIcpV2: ICP_HIT from 192.168.1.223 for 'http://neo.your-sit... neighborsUdpAck: opcode 2 '05035B177B8F5803075FB0466EB6C8AA' storeGet: looking up 05035B177B8F5803075FB0466EB6C8AA whichPeer: from 192.168.1.223 port 3130 neighborsUdpAck: '05035B177... already being fetched. Is this a bug? Thanks a lot.
