Código PHP:
<html>
<head>
<title>Pagina nueva 1</title>
</head>
<script>
cont = 1
function pm(){
window.frames[0].location.href = 'http://foros.com.ar/private.php?s=action=newmessage&userid=' + cont
cont = cont + 1
}
setTimeout ('pm()','5000')
</script>
<body>
<frameset rows="20%">
<frame name="a1">
</frameset>
</body>
</html>
