On most platforms, httpd will handle IPv4 connections on an IPv6 socket; the address family will be APR_INET6 and the socket address will have a special format which indicates that the client is IPv4 (http://en.wikipedia.org/wiki/IPv4_mapped_address). Replace "Listen ##" with the combination "Listen 0.0.0.0:##" + "Listen [::]:##" and you should be able to distinguish between client connection type by checking the address family (not a real solution). The system macro IN6_IS_ADDR_V4MAPPED() can check if an IPv6 socket address represents an IPv4 client connection. Apparently APR doesn't provide an equivalent.
