        The browser will not send this unless it knows it is talking to a
proxy;
        however, if it is an HTTP/1.1 aware browser, it will send a Host
header
        containing the target host.

        See the list for a couple of days ago for specific information on
        making use of host headers.

        Note the original way of handling transparent proxies requires that
        the IP packet be addressed to the true host, not the proxy, which
        requires special IP routing software on the proxy machine, at least.
        I'm not sure if this is still true if you enable host headers, but
not
        all browsers use them.

        I simply block port 80, which forces people to explicitly configure
a
        proxy, but this is an office network not an ISP.
