Ever experienced someone posting a huge URL on your comment section? Those long strings are not only ugly, but they might also break the design of your website on certain browsers.
The best solution for this problem is a WordPress plugin called WP-Chunk. It will basically transform a long URL like this:
http://www.domain.com/test/subfolder/?=123/article=?id8A133F52D0FD71AB86256C
into a smaller string like this:
http://www.domain.com/test/...56C
