The usual cache-control example is not complete. Try this:
// Cache-Control for HTTP 1.1, Expires and Pragma for older browsers
response.setHeader("Cache-Control", "no-cache; no-store;
must-revalidate; proxy-revalidate");
response.setHeader("Expires", "0");
response.setHeader("Pragma", "no-cache");
