Re: HTTP Host Request header and TC Connectors
My understanding is that this is really a client issue, rather than server. By the time a connector gets it, it's too late to do much about it. A little bit of research indicates that the user agents I have about will put the IP address in the Host header if the URI is specified by IP. That seems the only reasonable thing to do. The name of the host in that case is the IP address. I suppose that if you were doing something bizzare like HTTP over a unix domain socket you wouldn't have a host name of any kind. But that's pretty far out there. But, on the TC side, I don't think the connector should rewrite the header if it's empty.
