        Boycott sites that make pages uncacheable without
        justification, or with their commercial benefit
        being the only justification.

        There are other approaches, but if you need to ask
        you probably don't understand cacheing well enough
        to safely use them.

        Use external scripts to analyze the logs and something like wget
        to re-fetch the pages. However, some sites consider
        automatic fetching to be an illegal use of their web server and will
        block people suspected of doing it. To be legally safe you must
confirm
        that the sites for which you do this permit it before you attempt it
- you
        well find that the sites you most want to do it for are the sites
that
        are most likely to object.

        Also, there may be some dynamic content which is marked as cacheable
        but for which the server cannot handle an If-Modified-Since request,
        with the result that revalidating the page actually re-fetches it.
