623	IPv6 link-local addresses with zone id not usable in proxy_pass	launchpad.net/~lotheac		"nginx doesn't like IPv6 link-local addresses with zone identifiers (addresses like 'fe80::8:20ff:fe6a:64de%www1'; the zone identifier 'www1' here refers to the network interface).

First I tried with a literal address:
{{{
proxy_pass http://[fe80::8:20ff:fe6a:64de%www1]:5232/;
}}}
but that resulted in
{{{
invalid IPv6 address in upstream ""[fe80::8:20ff:fe6a:64de%www1]:5232/""
}}}

As an aside: I could work around this if it was possible to tell nginx to use getaddrinfo to resolve upstreams. If I put the address in /etc/hosts as 'foo' and use 'http://foo%www1:5232/' both curl and wget resolve the address correctly (because they just pass it to getaddrinfo), but nginx fails with:
{{{
no resolver defined to resolve foo%www1
}}}
and if I do define a resolver, it will try DNS queries, which is the wrong thing here. Is it not possible to use the system resolver?"	defect	closed	minor		nginx-core	1.6.x	invalid			SunOS www 5.11 omnios-8c08411 i86pc i386 i86pc	"nginx version: nginx/1.6.1
