Actually, RFC 2616 has been obsoleted in relevant parts by RFC 7230, which says any kind of authority MUST be put into host (unless the URL is absolute) and kinds of authority also include IPv4 address literials, IP address literials (especially IPv6) and hostnames. So by RFC 7230, IP addresses are put into host header. -Ilari _______________________________________________ Acme mailing list [email protected] https://www.ietf.org/mailman/listinfo/acme
