Friendly urls... What's your preference?

Explain in more detail how you envisage this working.

Well, the only part of the url that would be looked at (by the method) would be the number part. So,

/123/this-is-real/

would be the same as:

/123/this-is-not-real/

It wouldn't make a difference to the application, but when your app creates links (and displays them on the page) the url would appear correctly. When I say meaningless, I mean the application isn't checking up on it at all. It just ignores that part of the url.
