Are you shure, default level=0 ? I have squid 4.4; either started simply using "squid" or "squid -d 0". squid.conf does not contain any line debug_options ..... however, in all cases messages like 2019/03/22 18:06:04 kid1| SECURITY ALERT: on URL: edge-mqtt.facebook.com:443 2019/03/22 18:06:04 kid1| SECURITY ALERT: Host header forgery detected on local=31.13.85.2:443 remote=192.168.182.8:5623 0 FD 35 flags=33 (local IP does not match any domain IP) fill up cache.log. -- Sent from: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-Users-f1019091.html _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
