        Not always, as far as I know, David. I'm running a configuration here,
which has the following topology:

                                        +------------+
                                        | Proxy01 |
        +--------------+ +------------+
        | Redirector +----------------+
        +--------------+ +------------+
                                        | Proxy02 |
                                        +------------+

        The Redirector is a machine running a redirector, which makes a load
balance through the proxies (based in some factors) of the requests coming to
it's 3128 port.

        In this cenario, the clients shold neve send ICP requests to the
Redirector, not even requests of digests, so we should configure with both
no-query and no-digest.

        As you can see, ther IS some point in doing this. :-)
