I'm planning to Implement CDN(Content Delivery Network) of Amazon which is known as CloudFront in ASP.NET MVC3 with c#.
I've googled about it but little bit confuse about few things mentions below.

Is it compulsory that we have to uploads all static resources to CDN Network first and then we can use or Is it manageable by Amazon to crawl site static resources which is predefine folder or directory of sites?
Is Amazon automatic update its copies when we anything change in static resources or every time we have to upload updated resources to CDN network.
