A url shortening service (according to Wikipedia) makes a web page available under a very short URL in addition to the original address. A short URL obscures the target address and, supposedly, only "forwards" the request to the final page.
For the fun and the test, I’ve compiled a sequence of short urls that target each other in an infinite loop. The first one points to the second, which in turn points to the tird and so on... The last one points to the first one.
Here is the list: (Because it’s a loop, there is no beginning or end. Just click on any of those to start.)
