HOW CDN works

All,

I'm just new to this and have a basic understanding how CDN works? My questions are:

1. How does CDN sync data with web servers for video/images? If I have a user to upload a video to my site, will it get stored directly in CDN or it comes to my webserver first and then sync-ed with cache server?

2. How to have only the dynamic video/image delivered through CDN while the rest is served by a webserver?
3. How sync happens and who pays for the bandwidth for sync?


I'd appreciate if someone could explain this.
Regards,
Janakan Rajendran

For basic understanding
http://en.wikipedia.org/wiki/Content_Delivery_Network

A1. It will first come to your webserver.

A2. URL rewritting for example.

A3. You pay for the bandwidth. The sync is basically "Serve if you have in the cache else ask peer, cache, and serve"

I would suggest to contact of the CDN providers and have their pre-sales-engineer come and explain all to you onsite.

hope this helps.
