Shortened Links Leaking

Hi people
Is there a way that I can check to see what shortened link is leaking?
I shortened multiple links and yesterday noticed that one of them came through as the full URL- Any ideas?
kind regards

What exactly does "leaking" and "coming through" mean? The short url is just a redirect that will always be resolved to the original url in the surfer's browser.

If it's referrers you're talking about, then the referrer is generally always passed through a straight 301 or 302 redirect with most browsers. If you want to hide / fake referrers then you have to use a system like CPA redirector 2.
