Child pages, slugs and URLs

[RobA]

I just noticed (realized) that child/parent relationships are not "enforced" when using pretty URLs.

For example, I have this page:
http://www.cartocopia.com/portfolio/ascadia/

Which doesn't need the portfolio parent page in the url, and this also works:
http://www.cartocopia.com/ascadia/

and even this:
http://www.cartocopia.com/it/does/not/ma...g/ascadia/

Does anyone have any suggestion on how to enforce the URL structure and make only the first work?
