Please rune squid -k check and fix the errors it mentions. There are quite a few lines of the config below which are unnecessary or wrong in squid-3.3. I've mentioned below a few of the extra changes that are not easily detected like that.. > http_port 3128 > http_port 3129 > http_port 4711 > logformat squid %{%d.%m.%Y %H:%M:%S}tl.%03tu %6tr %>a %[un %Ss/%03>Hs %<st > %rm %ru %Sh/%<a %mt You should not re-define the native Squid log format. Please use a different name. Although its worth noting that this logformat is never being used anyway due to "emulate_httpd_log on". > hierarchy_stoplist cgi-bin ? > acl QUERY urlpath_regex cgi-bin \? > no_cache deny QUERY the above three lines can go. > cache_dir ufs /var/cache/squid 100 16 256 > cache_access_log stdio:/var/log/squid3/access.log > cache_log /var/logs/cache.log > cache_log /var/log/squid3/cache.log You can only have one debug log for Squid.

Then a single "never_direct allow all". But you have no cache_peer lines at all. So all these always/never routing rules are just a waste of CPU cycles and time. You can drop the always_direct and never_direct lines completely. Amos
