IPv4 & IPv6

[B.R.]

Add-on:

Besides, as I explained earlier, having generic 'listen' directives implies
some difficulties.

For example, I am using 2 virtual servers to serve content for the same
server_name, one listening on port 80, the other on port 443, allowing me
to serve cotnent for HTTP and HTTPS in different fashions.
Using generic 'listen' directive breaks that system and I'm stuck.

What would be an acceptable solution?
Thanks,
