I don't think there is a general way to detect the "back button",
since that's part of the browser, not of the HTML document.
For instance, with IE5, when you press Back, it generally does not
request the server, but read the page in its cache.
Here, we have looked for a solution to this problem for a long time,
and I don't think there is a solution that works with any browsers.
(IE5 behaviour is different of IE4 behaviour and different of Netscape
