Method Detail

addNoCacheHeaders

public static void addNoCacheHeaders(javax.servlet.http.HttpServletResponse response,
                                     int expire)

The code first sets the Expires header to a date in the past. This indicates to the recipient that the page's content have already expired, as a hint that it's contents should not be cached. The no-cache value for the Pragma header is provided by version 1.0 of the HTTP protocol to further indicate that browsers and proxy servers should not cache a page. Version 1.1 of HTTP replaces this header with a more specific Cache-Control header, but recommends including the Pragma header as well for backward compatibility.
