correct commands to enable nonssl, ssl, ipv6, spdy

[Ryan Brown]

Wanting to enable ssl+spdy+ipv6 on port 443, and ipv6 on port 80.

    server {
        server_name secure.domain.com;
        #
        listen [::]80;
        listen [::]:443 ssl spdy default ipv6only=on;
        #listen       [::]:443;
        #listen [::]:443 ssl default_server=on;
        #listen        [::]:443 spdy default ipv6only=on;
       [...]
      }

I've tried various methods, but the https isn't working.. whats the
correct command to enable all such options?
