I played around with a test installation of SS 2.2.3. I added a sub page to the default installation below "about us" with the title playground. Everything works as expected but then I noticed that the url to the sub page is "flat": I expected that a sub page also is visible as a sub document in the virtual directory tree (means I expected to see http://www.example.org/about-us/playground/) but it shows up as http://www.example.org/playground/.
Is it right that in SilverStripe you do not have paths like in static environments to structure things up? Or did I miss something?
