Hello, Should proxy_pass retry ipv4 if ipv6 fails? Currently (1.5.12), it does not, and there is no way to force proxy_pass to always use ipv4. Specifically, if a proxy_pass host has dual records (A+AAAA), proxy_pass seems to only try the AAAA. I'm considering submitting a patch if there is support for this. Thanks! -Jim P.
