a simple workaround, but one that pretty much prevents any caching
anywhere, is to append the URL for this file with a changing query
string, e.g. a timestamp. this is what it would look like:

<untested>
<a href="<dtml-var name="my_file">?x=<dtml-var expr="ZopeTime()"
fmt="%H%M%S">">My File</a>
</untested>
