Q306 Is there anyway to force the browser to reload the html page from the server and not from the browsers cache?

<script language="JavaScript"><!--
if (document.images)
    location.reload(true); // forces a reload from the server
else
    location.href = location.href;  // just reloads the page
//--></script>

<script language="JavaScript"><!--
function forceReload() {
    if (document.images)
        location.replace(location.href + '?' + (new Date()).getTime());
    else
        location.href = location.href + '?' + (new Date()).getTime();
}

var lastTime = location.search.substring(1) - 0;
if ((new Date()).getTime() - lastTime > 1000)
  forceReload();
//--></script>
