You can use javascript to send an AJAX query back to the server with the frame's source.

The javascript you could use is iframe.location.href where 'iframe' is the id attribute of your iframe.

Then you can send a callback to the server using ASP.NET AJAX (or another ajax call if you wish). Here is a good tutorial: http://ajax.net-tutorials.com/

You could do it all client side if you wanted to (untested code):

...
<body>

    <a id="yourAnchorId">Load It</a>

    <iframe id="youriFrameId" src="blank.html" width="500" height="400"></iframe>

    <script type="text/javascript">

        document.getElementById('yourAnchorId').onclick = function() {
            var frame = document.getElementById('youriFrameId')
            frame.src = "blah.aspx;"
            frame.location.reload();
        };

    </script>

</body>
...
