1) User enters www.example.com in their browser. Hostname sent to DNS for resolution

2) DNS resolves www.example.com to the Virtual IP address (VIP) of 10.10.10.10.

4) Array proxies request to selected real service.

5) Further requests from the client may be sent to the same or a different real service, depending on persistency configuration.
