Configuring DNS server selection (split DNS)

You can configure Traffic Server to use multiple DNS servers depending on your security requirements. For
example, you can configure Traffic Server to look to one set of DNS servers to resolve hostnames on your
internal network, while allowing DNS servers outside of the firewall to resolve hosts on the internet. This
maintains the security of your intranet, while continuing to provide direct access to sites outside your
organization.
You specify the rules for performing DNS server selection (also called split DNS) in the
file. Traffic Server enables you to specify this selection based on the destination domain, the destination host,
or a URL regular expression.

To configure DNS server selection:

1. Telnet into the HP web cache appliance and select Shell Access as described in
