Hello, I'm using a squid configured as proxy. According to the cache log, squid is doing a reverse dns lookup for client ips: 78,3| dns_internal.cc(1794) idnsPTRLookup: idnsPTRLookup: buf is 42 bytes for SOME_SOURCE_IP I'm only using the following configuration parameters that might be relevant for this issue. external_acl_type acl aclname src acl aclname dst acl aclname dstdom_regex acl aclname port acl aclname proxy_auth acl aclname external acl aclname url_regex Any ideas why squid is doing PTR lookups anyway ? _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
