Removed white "Establishing debug connection" page.
<html>
<head>
<script type="text/javascript">
var req;
function connect() {
req = new XMLHttpRequest();
req.onreadystatechange = testconnection;
req.open("GET", "testConnection" + window.location.search, true);
req.send(null);
}
function testconnection() {
if (req.readyState == 4) {
if (req.status != 200) {
window.setTimeout(connect, 200);
} else {
window.location = '../wrt_preview_main.html';
}
}
}
</script>
</head>
<body onload="connect()" style="color: silver;">
