As Excelerator processes browser requests, it uses the DNS system to obtain the IP addresses of origin Web servers.
Because the DNS names in browser requests are not always straight-forward, Excelerator tries various permutations to try and locate the Web server. As a result, DNS names ending with domain extensions other than .com, .org, and so on, are sometimes resolved in unexpected ways.
If users of your appliance are experiencing this problem, you can customize how the appliance resolves DNS names.
