        OK, I think I am begining to fet a handle on this. Thanks for being
        such a patient teacher.

        I am trying to do this, but it's not working. I am certain it's because
        of my lack of understanding. here is teh relevant portion oof my
        squid.conf file:

        refresh_pattern ^ftp: 1440 20% 10080
        refresh_pattern ^gopher: 1440 0% 1440
        refresh_pattern .gif$ 4320 90% 8640 override-expire
        override-la
        stmod
        refresh_pattern .jpg$ 4320 90% 8640 override-expire
        override-la
        stmod
        refresh_pattern . 2880 60% 4320

        I decided to get aggressive about .gif's and .jpegs, at least _I think_
        this is aggresive.

        Still I thought that the last line would cause any page without the
        information you mention above to cached. Am I wrong?

        I want to _agresivly_ cahce pages. I would arther err in the directiion
        of breaking things such as hotmail , in order to be able to serve more
        static vendor information sites locally.

        Any sugestions as to a better set of rules to put here?

        I started there, but some of the replies I got said it was "too
        techniacl". and that I should look at access.log instead :-(

        Thanks again for all of your patient help to such a newbie on this.
