Hi, I have just update to the latest version, and the results are clear: cat /var/log/squid/access.log | awk '{print $4}' | sort | uniq -c | sort -rn 486561 TCP_MISS/200 89612 TCP_MISS/304 52123 TCP_MEM_HIT/200 40408 TCP_MISS/206 36267 TCP_MISS/302 20904 TCP_MISS/204 12246 TCP_IMS_HIT/304 12171 TCP_MISS/404 10533 TCP_MISS/301 9145 TCP_MISS/000 6004 TCP_OFFLINE_HIT/200 ...... It's said that MISS/301, MISS/303 are not cacheable without special instructions. What are those SPECIAL instructions?
