I'm an italian researcher in Content Delivery Networks. From two weeks I've
started
my work about CDN and I've some doubts about DNS Requesting Routing. I read
the relative draft, but I'd 
like to see an example.
Can you hel me about other request routing mechanism too?
Can you show me some pregnat whitepaper or other?
Thanks a lot
