Use "HEAD" instead of "GET" when opening the port. ie...

HTTP/1.1 200 OK

That works with rebol.com, anyway, though not with Yahoo. You may
need to supply more info in Yahoo's case, or it maybe it's just
because Yahoo refuses to supply just the header. But with a bit of
luck, it won't be Yahoo's header you're after. (:
