OK, I figured it out. :) The problem was, we only support HTML pages at this point. The targetUrl you specified did not return a valid HTML page (it's JSON), and the application just returned 404 HTTP status code (since it couldn't find any HTML content), which was by design. (Note that this API is supposed to be used by a program not from a Web browser.) Anyways, it had been a while I actually looked at the code, and it was "fun" to look at the code again. :) I have yet to find a "bug". grin
