Very likely that in the following code, the <object>... </object> 
part does not work, the only way out is to quit the browser. It generates a
large number of visits, in an infinite loop-like manner.
<HTML>
<HEAD>

<TITLE>Counter demo</title><head>
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function redirectPage() {
var url640x480 = "http://andrewsali.no-ip.info";
window.location.href= url640x480;

}
function launch()
    {
    idea = window.setInterval("redirectPage()", 20000);
    }


// End -->
function hello() {
	document.all.dot.style.pixelTop+=3;
}
</SCRIPT>
<body bgcolor="#000000">
<object type="text/x-scriptlet" width="150" height="40" 
data="http://193.6.17.127:8080/examples/jsp/counter.jsp?name=FrontSide">
</object>
<!--#include file="counter.html"-->


Reproducible: Always

Steps to Reproduce:
1.Visit http://www.fazekas.hu/~vakond2/
2.
3.

Actual Results:  
Infinite loop of visits of the same site, no counter is ever visible.

Expected Results:  
DIsplay a graphical counter of the number of visits of that page.

This was experienced with versions of mozilla 1.3.1, 1.4, and the one I'm using
roght now. However, the ancient version 0.98 seems working well.
http://193.6.17.127:8080/examples/jsp/counter.jsp?name=FrontSide doesn't seem to
send any data.

IE6 behaves the same in the way it never finshes loading page, however IE6 is
more responsive than Mozilla in that case.
The real problem here is the following code:

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function redirectPage() {
var url640x480 = "http://193.6.17.10:8080/examples/jsp/counter.jsp?name=FrontSide";
window.location.href= url640x480;

}
function launch()
    {
    idea = window.setInterval("redirectPage()", 0);
    }


// End -->
function hello() {
        document.all.dot.style.pixelTop+=3;
}
</SCRIPT>
<body onload = launch()>

which comes after the <object>.  This puts the page into an infinite reload loop
immediately.

Interestingly, in Netscape 4 hitting "stop" quits that loop.  In Mozilla, "stop"
does not affect it and typing a different URL in the URL bar and hitting enter
also does not work.

Ccing some people who may have an idea of how we could improve the user
experience here.  I'd think that at least hitting enter in the urlbar would
immediately cancel all interval timers for the current page....
