        I think the other thing you have to remember is that the
        most popular sites tend to be the commercial portals, and
        these are interested in attracting users who will spend
        money with their advertisers. It is in their interests
        to attract rich users and to continually change the content
        of their pages so as keep the users interested and keep
        sending new adverts.

        If you cannot afford bandwidth for this, the chances are
        your users are not going to spend large amounts of money
        with their advertisers, so it is unlikely that they will
        re-design their sites to use network infrastructure
        efficiently for your benefit.

        Unfortunately many of those in whose interests it would be
        to do things efficiently don't have the technical knowledge
        or don't have the level of access to the server needed to
        set HTTP meta data (using META tags is usually pointless).
        Chances, are, though that your subscribers aren't accessing
        these sites, anyway.

        Your real problem, then, is not a technical one with squid,
        put a commercial one in convincing content providers that
        it will increase their profits if they make it easy for
        your subscribers to access their sites.

        If you do use technical solutions, you have to fight
        commercial factors with brain power, which means
        getting a deep understanding of caching and continually
        tweaking your configuration as the content providers
        change their sites.
