Uniform Resource Locator
A URL is a URI that, "in addition to identifying a resource, provides a means of locating the resource by describing its primary access mechanism (e.g., its network location)".
In theory "Cool URLs don't change". But that's never quite true.

- a 5-word Lexical Signature generated based on Tf Idf should be sufficient. (Like a Google Whack.)
- having your own Domain is a good risk-reducer
