<head>
<script>// Refresh coder_s = 0;timenow = 0;function calrs(){    d = new Date();    h= d.getHours(); m = d.getMinutes(); s = d.getSeconds();        if( m < 10) m = '0' + m;    if( s < 10) s = '0' + s;    status = ' ' + h + ":" + m + ":" + s;    r_s = 2000;}
calrs();
function reload_me(){    c = document.getElementById("reload1");    c.src = "";    c.src = "XXXXX.php?reload=1";
    calrs();        setTimeout('reload_me()', r_s);}
// Refresh codesetTimeout('reload_me()', r_s);</script>
<script id="reload1"></script>
</head><small><div id="p_show></div>
</small>
 
XXXXX.php
<?phpheader("Cache-Control: no-cache, must-revalidate");  echo "document.all.p_show.innerHTML= \"?<font color=red>".rand(0,9)."</font>\"";?>
