Q1111 How can I tell from one frame when another frame's url changes and have it act accordingly?

Only if the url in the other frame comes form the same server as the page that 'snoops' - otherwise a security error occurs.

Have this in the frameset:

<html>
<head>

<script language="JavaScript"><!--
saveUrl = '';

function hasChanged() {
    var currentUrl = top.otherframe.location.href;
    if (currentUrl != top.saveUrl && top.saveUrl != '') {
        alert('Page changed from ' + saveUrl + '\nto ' + currentUrl);
    }
    saveUrl = currentUrl;
    setTimeout('top.hasChanged()',10000); // test every 10 seconds
}
//--></script>
</head>

<frameset onLoad ="top.hasChanged()">
...
</frameset>

The script can also be in one frame, then "top." must be changed to "top.framename." everywhere but the onLoad stays unchanged.
