How can i get this kind of urls

[eluser]Eugen[/eluser]
Hi guys, i am stuck with this problem: How can i have urls like these:

Code:

mytld.com/europe
mytld.com/spain
mytld.com/barcelona
mytld.com/barcelona-aquarium

As you can see i do not want to use mytld.com/spain/barcelona/barcelona-aquarium

I want to have only one url segment witch can be a continent, a country, a city, or a point of interest...

How can i make a difference between them and redirect to the propper controller/view ???

Thanks for any suggestion or code sample you might post here!
