That is a HUGE difference. That's a concern, but you can mitigate it slightly by caching the results of URL expansion. Also, I suspect most URL-shorteners expect to be bombarded with requests and are engineered accordingly. I have seen a CAPTCHA thrown up from the search page, but I've never seen a goo.gl HEAD request reply with anything other than 404 or 301. Regards, Dianne.
