Hi,

I am having masterpage and using iframes. Everything is working fine except if submit activity happens on iframes, its not reseting the session timeout?

<script type="text/javascript">
function SessionExpireAlert(timeout) {
    var seconds = timeout / 1000;
    document.getElementsByName("secondsIdle").innerHTML = seconds;
    document.getElementsByName("seconds").innerHTML = seconds;
    setInterval(function () {
        seconds--;
        document.getElementById("seconds").innerHTML = seconds;

    setTimeout(function () {
        //Show Popup before 20 seconds of timeout.
        $find("mpeTimeout").show();
    }, timeout - 20 * 1000);
    setTimeout(function () {
        window.location = "Expired.aspx";
    }, timeout);
};

</script>

Question:
What to do if there is any activity in top and right frame, it will reset the session timeout without refreshing the full page? If parent page refreshes, everything is working fine?
