URL redirection allows web site owners with long URL addresses or links (like http://www.insanely-long-and-hard-to-spell-domain.com/cgibin/123/main.html) to have a short URL address that will automatically redirect web visitors to your real page. The short URL address acts like an “alias” for the long URL address where your content is located.
 
A lot of people don’t like to click on long complicated links or can’t remember complicated domain names. URL redirection is a solution for overcoming the these obstacles.
 
Note: There is a newer form of URL redirection called frame forwarding, which gives you benefits such as search engine friendly HTML tags, hiding ugly URL addresses, URL stickiness (your own “framed” URL stays in the URL window of web site you referred the visitor to...very cool!) and ad tracking.
 
One of the best services for frame forwarding URL redirection is a product called NameStick.
