Ok. I changed the line to go to port 80, instead of port 3128. I read that that is a better choice since this is a reverse proxy. Here's the line I changed: cache_peer prdseoproxy02.corp.bbi.com sibling 80 3130 But I'm still having grief. Sending a song to the first sibling gives a TCP_MISS. The other sibling gives a UDP_MISS. Sometimes I see this: 1347379698.716 0 10.2.12.185 TCP_MEM_HIT/200 583 GET http://prdseoproxy02.corp.bbi.com/squid-internal-periodic/store_digest - HIER_NONE/- application/cache-digest But not always. Ready to pull my hair out!
