HTTP_HOST is the value of the Host: HTTP Header field that the browser sent to the server, for purposes of distinguishing multiple hostnames on a single machine/IP-address. Also, older browsers which use HTTP/1.0 don't have to send a Host header, so HTTP_HOST might not be defined. Better to use SERVER_NAME.
