Hi,

Attached is a simple patch to proxy\_pass to an IPv6 upstream.  
It currently works only with a variable. proxy\_pass ::1; wont’ work for  
instance.

but this will :

set $addr “[::1]:8080”;  
proxy\_pass http://$addr;

You also need to add --with-ipv6 to your configure line.

Happy hacking,  
Matthieu.

This should be addressed in ngx\_parse\_url(). The ipv6 cleanup is  
planned somewhere after 1.1.x become stable.
