723	resolver ipv6=off doesn't work with https upstreams	Arrix Zhou		"
{{{
    location ^~ /xxx {
        resolver 8.8.8.8 ipv6=off;

        proxy_set_header   Host www.mydomain.com;
        proxy_pass https://www.mydomain.com;
    }
}}}

Even with ipv6=off, error log reports failure to connect to IPv6 address.

{{{

It works if I change https to http."	defect	closed	minor		nginx-core	1.6.x	invalid			Linux ip-172-31-4-219 3.14.33-26.47.amzn1.x86_64 #1 SMP Wed Feb 11 22:39:25 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.6.2
