- redirUrl is the url to a non password protected area (logout success page).
- you might wish to increase the redirect timer (currently 200ms).

function logout(secUrl, redirUrl) {
    if (bowser.msie) {
        document.execCommand('ClearAuthenticationCache', 'false');
    } else if (bowser.gecko) {
        $.ajax({
            async: false,
            url: secUrl,
            type: 'GET',
            username: 'logout'
        });
    } else if (bowser.webkit) {
        var xmlhttp = new XMLHttpRequest();
        xmlhttp.open("GET", secUrl, true);
        xmlhttp.setRequestHeader("Authorization", "Basic logout");
        xmlhttp.send();
    } else {
        alert("Logging out automatically is unsupported for " + bowser.name
            + "\nYou must close the browser to log out.");
    }
    setTimeout(function () {
        window.location.href = redirUrl;
    }, 200);
}
