        I thought of it this way: if there is a cache hit, then the connection
        is not established (most of the time, when the DNS entry is not
        expired). But when there is a miss, the page is fetched directly. This
        should already cut down telephone charges. But you're right that this
        might not be enough.

        The problem with the "dial by hand" senario is that the user might not
        get the desired page even if it is in the cache, because the DNS entry
        has expired.

Lars.
