Set the Following before sending any content,
response.setHeader("Cache-Control","no-cache");
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", 0);
This prevents caching.
Additionally the Servlet engine may also be configured
to cache the page. Check for this also in the confog
files.
