I have two hosting services. One is already in use and has domain example.com. It also has a sub-domain called order.example.com.
Second hosting service is under Amazon (EC2).
How can I use order.example.com sub-domain in Amazon virtual hosting service?
So when user goes to the example.com website and clicks the order.example.com link it redirects to Amazon server, but keeps the url as it is.
I want it to feel like that user hasn't redirected anywhere from example.com. Can I assign same domains to multiple servers?
