Hello list. I described this issue a few days ago on IRC and no-one could help me, so I am now turning to you. Here's my problem: I run two squid servers, siblings with each other, let's call them A and B. When clients send requests to A, and A thinks B has the resource cached, but in reality B doesn't, the client will get a 504 error with the message: “Valid document was not found in the cache and ‘only-if-cached’ directive was specified.” Vice versa if clients send requests to B. I believe that A should catch this error and fetch the resource directly, but instead it forwards it to the client, and I cannot figure out why. I am not using allow-miss. What confuses me even more is that this didn't happen a month ago, with the same setup. Below is my squid.conf for A. The squid.conf for B is the same, but with B swapped for A in the cache_peer directive. acl localnet src 10.0.0.0/8 acl localnet src fc00::/7 acl localnet src fe80::/10 http_access allow localhost manager http_access deny manager http_access allow localnet http_access allow localhost http_access deny all http_port 3128 icp_access allow localnet icp_access allow localhost icp_access deny all icp_port 3130 cache_dir aufs /var/cache/squid 16000 64 256 coredump_dir /var/cache/squid refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 cache_peer B sibling 3128 3130 |
