This is the code I'm using to disable refresh on IE and firefox (This works well for F5, Ctrl+F5 and Ctrl+R)

<script language="javascript" type="text/javascript">
    //this code handles the F5/Ctrl+F5/Ctrl+R
    document.onkeydown = checkKeycode
    function checkKeycode(e) {
        var keycode;
        if (window.event)
            keycode = window.event.keyCode;
        else if (e)
            keycode = e.which;

        // Mozilla firefox
        if ($.browser.mozilla) {
            if (keycode == 116 ||(e.ctrlKey && keycode == 82)) {
                if (e.preventDefault)
                {
                    e.preventDefault();
                    e.stopPropagation();
                }
            }
        } 
        // IE
        else if ($.browser.msie) {
            if (keycode == 116 || (window.event.ctrlKey && keycode == 82)) {
                window.event.returnValue = false;
                window.event.keyCode = 0;
                window.status = "Refresh is disabled";
            }
        }
    }
</script>
