D*ng, LiquidSummer. I've been using this service for almost a year with no problem, and you broke it. :)

It appears that, because it recursively calls it, the call eventually times out. (Google App Engine has this time limit of 10~30 seconds.) I'm not sure if I'll have a solution for this, but I can at least catch the exception. I'll need to look into it further.

Thanks for finding this bug!

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
