You need to get the server to attach an Expires header, which is
trivial if you're using Apache and the mod_expires.c plug-in.
However, be warned; the Netscape daylight savings time bug causes
the expiration date to be interpreted as 1 hour ahead of what you
actually request.
I've also seen Netscape mis-read an expires header that was 400 seconds
into the future and set it to 1 day in the past. doh!
