Hello, we use squid 3.4.9 as proxy for our company with ipv4 and ipv6 dual stack. It works good, but if a destination has an A and AAAA record and the webserver isn't reachable via ipv6, squid generates an error page instead of trying a connection via ipv4. One example is the url: https://ssl.ratsinfo-online.net/pirna-ri/logon.asp where squid tries to reach the webside via the ip 2001:8d8:87c:5f00::6e:72d6, but without success, because it isn't reachable. Now I want, that squid does a fallback to ipv4 after connect_timeout, but squid returns an error page (ERR_CONNECT_FAIL) to the client. -- Regards Dieter -- I do not get viruses because I do not use MS software.
