Basically all HTTP/1.0 servers support (if only to ignore) a Host: header,
and it has existed since before HTTP/1.1 came out. Still, if the server
is improperly set up you might see that result. Have you tried disabling
the Host: header (with the -0 -H Host: options) and seeing if that solves
the problem? It could also be that the URL you are using doesn't support
HEAD requests.
