We pass information from page to page on what is called the URL. Our use of the URL is normal for a dynamic site and you should have seen it often. The reason for the short URL feature is when you provide a link to be used by someone who is external to your site the shorter it is the better. Using a short URL setup screen you will be able to correlate a long URL of a nested page on your web site with a number to use for triggering a short URL.
