LispURL.com issues a LispURL for any real URL entered through the main page or the bookmarklet. From that moment on, whenever someone requests that LispURL, LispURL.com will redirect the request to the original URL entered.
For example, when, earlier, I submitted http://www.gnu.org/licenses/ on the main page, LispURL.com returned the LispURL http://lispurl.com/cddar, which from then on started to redirect requests to http://www.gnu.org/licenses/
One of the main practical appeals of URL redirection is that it produces URLs that are textually short enough to be used on Usenet and in e-mail without getting wrapped around to fit a line length limit. The line-wrapping of long URLs may render them virtually unuseable with some Usenet and e-mail user agent software.
Lispers may also like to use LispURLs as a subtle way to spread the Lispy meme. Of course, a knowledge of Lisp, or programming in general, is absolutely not required to use LispURL.com
In addition to the basic usage described above, LispURL.com will also allow extra path information to be provided with LispURLs.
For example, when http://lispurl.com/cddar points to http://www.gnu.org/licenses/ , then http://lispurl.com/cddar/gpl.html will append the extra /gpl.html to the stored URL and redirect you to http://www.gnu.org/licenses/gpl.html.
Recommended If you add the LispURL.com bookmarklet to your browser bookmarks, you can create a new LispURL for the currently visited page by just calling up the bookmark.

The format of LispURLs is derived from a set of Lisp operators as described in lispurl.com/cadr. The Common Lisp dialect described in that link defines "only" 30 of these operators, but in some implementations of some dialects of Lisp, every single one of our c...ad...r links would name a predefined function.
