I was trying to load pages changing the last value of the url. It seems to work only with the last number (j=19). I don't undestand why it seems to skip the other pages.
<!DOCTYPE html>
<html>
<head>
<script>
function newIP(n) {
window.location.replace("@@@@@:"+n)
}
</script>
</head>
<body>
<script>
var j;
for (j=0; j<20; j++) {
window.setInterval(newIP(j), 1000);
}
</script>
</body>
</html>
