That basically substitutes HAProxy for BIND, with the added
disadvantage of making an extra socket copy of every byte that is
proxied. Nothing that takes a static configuration and reloads works
in an environment where the configuration changes at intervals
measured in (sometimes fractions of) seconds.
Our backend routing decisions really have to be done from C++, which
is why we use Squid now and why I was looking at doing a varnish+vmod
solution. But I guess it isn't possible yet. :(
We did solve the immediate problem (IPv6 support) by upgrading squid.
It still doesn't use SMP properly, but that's less of an issue.
I will keep checking from time to time as I think varnish is great and
would like to see us give it a real shot.
