My guess is that the url you're providing is not at the "same origin" as
the url where your page was loaded from, i.e., it's a cross-domain request.
Even if you specify cross-domain, you'll fail in that case, because there
is no transport available that knows how to issue a synchronous,
cross-domain request. For a synchronous request, only the XMLHttp transport
can be used, and it will only work for a same-origin request.
