I'd like to get the security zone (Internet zone / local intranet) for a number of URL's which are in the same domain. I thought the best solution would be to get this through iFrame. I know that the statement value = frames.isTrustedIE(); is not possible! So could you give me the missing puzzle to get working this? 
. Thank you very much 
. Here is the following code!
<html>
<head>
<script type="text/javascript">
function isTrustedIE(){
try{
new ActiveXObject("Scripting.FileSystemObject");
}
catch(e){
return false; //untrusted
}
return true; //trusted
}
function getZone() {
var value = new Array();
var text = new Array();
var frameNames = document.getElementsByClass('iframeNames');
for(var i = 0; i < frameNames.length; i++) {
value[i] = frames[i].isTrustedIE();
if(value[i] == true) {
text[i] = "Trusted (Local Intranet)";
}else {
text[i] = "Untrusted (Internet Zone)";
}
} //end for
var showText = getElementsByClass("zone");
for(var i = 0; i < showText.length; i++) {
setText(showText[i], text[i]);
};
} //end getZone()
function setText(showText, text) {
showText.innerHTML = text;
} //end setText
if(document.getElementsByClassName) {
getElementsByClass = function(classList, node) {
return (node || document).getElementsByClassName(classList);
};
}
</script>
</head>
<style type="text/css">
tr:nth-child(2n) {
background-color: #ddd;
}
.format {background-color: #ffff;}
#formatierung {
margin-left: 10px;
margin-top: 30px;
font-family: Arial;
font-size: 13px;
}
</style>
<body>
<iframe src = "http://example.com" class = "iframeNames" width = "0"
height ="0"></iframe>
<iframe src = "http://example.com/index/" class = "iframeNames" width = "0"
height = "0"></iframe>
<script type = "text/javascript">
window.onload = function() {
getZone();
};
</script>
<div id = "formatierung">
<table width = "100%">
<tr class = "format"><td><h2>System</h2></td><td><h2>Check Security-Zone</h2></td></tr>
<tr><td>example1</td><td class = "zone"></td></tr>
<tr><td>example2</td><td class = "zone"></td></tr>
</table>
</div>
