Hi Hershel,

What I do usually is append a string to the current URL, so as to
bypass even the browser's own cache.

Something like that:
(watch out for any wrap)
function refresh() {
    now = new Date();
    str = now.getTime().toString();
    l = this.location.toString();
    this.location.href= l + ((l.indexOf("?")==-1)? "?" : "&") + str;
}

Call refresh() whenever needed.

Actually it's not that good a method, because if you call refresh()
from a refreshed page, you get another append on the first, but it can
be a good basis for what you're trying to do... and in my experience
you're sure to have a good refresh.
