<title>Upgrade Insecure Requests: top-frame navigation inside iframe (no upgrade expected)</title>
</head>
<body>
<!--
This is a bit of a hack. UPGRADE doesn't upgrade the port number. So if the
url is upgraded, the url becomes invalid (https over the http port). The
expected behavior is that the url is not upgraded and the page loads.
