This IE AuthSub issue is not because of the IFrame, the transferToken
approach didn't make a difference.
I tried placing the google.load('gdata', '1.10'); call in a button
click event. Here's the code:
<html>
<body>
<img src="logo-small.png" />
<script type="text/javascript" src="http://www.google.com/jsapi";></
script>
<script type="text/javascript">
function loadGData() {
google.load('gdata', '1.10');
}
</script>
<input type="button" value="Load GData" onclick="loadGData();" />
</body>
</html>
If you try this, when you click "Load GData", the page is cleared and
nothing really happens. If you look at the page source after clicking
the button you see the following:
<script src="http://www.google.com/uds/?file=gdata&v=1.10"; type="text/
javascript"></script>
This is what would happen if document.write was being used and would
explain a few things.
Eric, does your AjaxLoader module use google.load() from the jsapi?
