I don't think the above will work, for the Expires header at least.
Supposedly it has to be in a specific format, including using GMT.
Here's what I use:
resp.setHeader("Expires", "Mon, 01 Jan 1990 06:00:01 GMT");
resp.setHeader("Cache-Control", "no-cache");
resp.setHeader("Pragma", "no-cache");

I haven't done extensive testing, but the above use of the API methods
seem to work fine for me.
