As you said HTTP 1.0 doesn't mandate the header. Also there could be HTTP
1.1 clients who doesn't sent the Host header properly. However most clients
(even HTTP 1.0 clients) will send the header. I tested this with curl, FF,
Chrome and using an Axis2 client.
I'm also little skeptic about the call to the NhttpUtil.getHostname. It
returns the IP address when tested on my machine. But there doesn't seem to
be anyway in the HTTP Core API to get the full request URI. I'm further
looking into this.
