Create a list of country code top level domains (ccTLDs) that have
country-specific standardised subdomains.
ccTLD1 "subdomain [subdomains...]"
ccTLD2 "subdomain [subdomains...]"
This directive is only available for use in the global
(interchange.cfg) configuration file,
and will affect all websites running under the Interchange installation.
It will not work in a website's local (catalog.cfg)
This filter was introduced in version 5.5.2,
and is therefore not available for use with any earlier Interchange version.
This directive is used to define a list of country code top level
domains (ccTLDs) that have country-specific standardised subdomains.
One example is the "uk" ccTLD with its "co.uk",
"net.uk" and other subdomains.
The list is used by the DomainTail facility
to qualify the session ID.
See the DomainTail documentation for more
Interchange versions 5.5.2 and later are supplied with a
global "subdomains.cfg" file that should be
into the global (interchange.cfg) configuration file.
