Hi! Can I force certain destinations to be reached using ipv4 only? I found this: https://superuser.com/questions/994728/force-squid-to-connect-to-sites-over-ipv4-rather-than-ipv6 and implemented: acl apiendpoint dstdomain api.endpoint.example tcp_outgoing_address 193.175.73.216 apiendpoint 193.175.73.216 being the IP of my squid's extern a interface. But alas, It doesn't work. Sometimes an ipv4, sometimes an ipv6 address is being used...
