You cannot build a CDN with two servers. A real Content Delivery Network (CDN) has servers on several continents, and routes the end users to a server near him by means of TCP/IP Anycast, geo-aware DNS, HTTP redirects and HTTP proxying, or more likely combinations thereof. Your question is vague to the point of being un-answerable. If you just want to have both servers serve files for | |||||

You can do DNS round-robin "load balancing". But for a simple CDN solution check out http://code.google.com/p/cirruxcache/ | |||

That's quite a big question your asking, and not an easy one if your not familiar with DNS or Apache, but first can I ask what you're looking to achieve by using a CDN? Do you have a current issue you're working around by investigating a CDN? It's not what I would call a CDN, but the quickest way to achieve want you have described is to have a caching proxy (squid to name a common one) , which you point domain1 to. Then the proxy goes off to domain2 when it needs content it doesn't have in the cache. If a visitor hits the proxy and it already has the file they are asking for in cache, it will be served from there rather than domain2. | |||
