You can: enable the DNS section of debug logging in cache.log and watch the DNS lookups in progress. tcpdump/wireshark the data stream and see who is doing lookup for domains. log on the local networks DNS server to see who is looking up what when. (in recent squid) look in squids access.log to see where its requesting traffic from for any given request. use 'squidclient mgr:ipcache" to see what squid has resolved each domain to. Amos
