Hi, For making a page expire when client presses back button we need to put following code in servlet response.setDateHeader("Expires", 0); response.setHeader("Pragma", "no-cache"); response.setHeader("Cache-Control", "no-cache"); response.setHeader("Cache-Control","post-check=0, pre-check=0"); response.setDateHeader("max-age", 0); But above is not working with my pages, when I checked it with response.containsHeader("Cache-Control"); This is returning false. That means there is no Cache-Control in my response header. That may be the reason my pages are not getting expired. Can somebody help me out. Regards,
