I have been using a WordPress plugin for awhile called Pretty Link Pro which provides a ton of awesome features including a link shortener such as tinyurl.com. When using the URL shortener you can actually configure Pretty Link Pro to use a different domain which would be a benefit if your URL is long similar to www.question-defense.com. I have been using link.as so instead of providing shortened links such as http://www.question-defense.com/1ce I can provide links such as http://link.as/1ce which you can see is a lot more user friendly when providing links to others. One thing I wanted to ensure was the fact that Google was not crawling content on the http://link.as URL which is possible simply by Google finding the shortened links on places like Twitter. Below I describe a .htaccess modification that will redirect any traffic to one URL to another while including any trailing text.
