Cache-Control may not work on IE4 if you haven't specified to use HTTP1.1 in
Internet Options.../Advanced Tab/HTTP1.1 Settings since Cache-Control is a
HTTP1.1 feature.
BTW if you call setHeader twice with the same name, will it override the
previous value?
If the setHeader is not working, you may try to use the META tag
"HTTP-EQUIV" in your HTML output.

You can also try adding
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Cache-Control", "no-store");
but IE 4 may defeat you on all of these. See the archives for details,
but IE has a bug in which no-cache headers don't work under some
circumstances.
