How do you control if someone is logged on? Do you store a user token in the session? Use Form Authentication and rely on AuthProvider? If it is session based, you have to call Session.Clear or even Session.Abandon. More details, please.

XML

<script type="text/javascript">
    function preventBack() { window.history.forward(); }
    setTimeout("preventBack()", 0);
    window.onunload = function () { null; };
</script>

Use this on the Login page to prevent the history forward. And on the Hime page place the below snippet:

XML

<script type="text/javascript" language="javascript">
    function DisableBackButton() {
        window.history.forward();
    }
    DisableBackButton();
    window.onload = DisableBackButton;
    window.onpageshow = function (evt) { if (evt.persisted) DisableBackButton(); }
    window.onunload = function () { void (0); };
</script>

Hope this helps.
Thank you :)
