Examples
Consider the following DNS server selection specifications:
dest_domain=internal.company.com named=255.255.255.255:212 255.255.255.254 def_domain=company.com search_list=company. com company1.com
dest_domain=!internal.company.com named=255.255.255.253
Now consider the following two requests:
http://minstar.internal.company.com
This request matches the first line and select DNS server 255.255.255.255 on port
212. All resolver requests will use company.com as the default domain, and company.com and company1.com as the set of domains to search first.
http://www.microsoft.com
This request will match the second line. Therefore, Content Gateway selects DNS server 255.255.255.253. No def_domain or search_list was supplied, so Content Gateway retrieves this information from /etc/resolv.conf.
