Put this JavaScript on the iframe page and call it.

function refreshWindow() {
    if (parent.window.location.href.indexOf("#") == -1) {
        parent.window.location.href = parent.window.location.href + "#";
    }

    parent.window.location.href = parent.window.location.href.replace("#", "");
}
