Other way is to place small image eg. 10x1 pixel to page and into very long
html content time by time put javascript for resizing image width. Some like
this:
<html>
<head>
<script>
function resizeit(x) {
image=getElemtById("bar");
image.width=x;
}
</script>
</head>
<body>
Loading: <img id="bar" src="some_green_image.gif" height=10 width=1>
<p>...some long html content here</p>
<script>resizeit(5)</script>
<p>...some other long html content here</p>
<script>resizeit(10)</script>
....
<script>resizeit(100)</script>
