Hello guys, I'm facing the same issue Tom Tux have in this thread: http://www.squid-cache.org/mail-archive/squid-users/201008/0631.html As far as i understood, the TCP_DENIED/407 is normal in authenticated environments. My question is: Do these TCP_DENIED/407 count in the "client_http.errors", at the cachemgr statistics? In about 50 req/s (http.requests), i'm seeing about 15 req/s (http.errors). If not, my question changes to: what goes on "client_http.errors"? The description of the counter is not very clear. Thanks! Carlos
