<title>IFrame Resize Sample</title>
<script type="text/javascript" src="FrameManager.js"></script>
</head>
<body>
<div>The Following is an iframe:</div>
<iframe id="ifrSample1" scrolling="no" frameborder="0" src="www.paginaExterna.com" style="margin:0px;width:100%;height:100px" onload="FrameManager.registerFrame(this)">
</iframe>
</body>
