Does Hiawatha support IPv6? I think not 'cause you convert IP-addresses strings to unsigned long (32-bit). But maybe I'm mistaken. If not, will Hiawatha support IPv6 in the (near) future?
This is not just a feature request.. it prevents some users to test/use the secure Hiawatha webserver in high-end (secure) IPv6 environments. Those users probably turn to Apache, making the environment less secure.
It is like Malcolm X said: "The future belongs to those who prepare for it today."
