LocalLB::DNSCache::get_forward_zone

Introduced : BIG-IP_v11.5.0
Gets the names of forward zones for a set of DNS caches. A given zone name should only use the symbols allowed for a fully qualified domain name (FQDN), namely ASCII letters &aposa&apos though &aposz&apos, digits &apos0&apos through &apos9&apos, hyphen &apos-&apos, and period &apos.&apos. For example &apossite.example.com&apos would be a valid zone name. A DNS Cache configured with a forward zone will forward any queries that resulted in a cache-miss (because the answer was not available in the cache) and which also match a configured zone name, to the nameserver specified on the zone. If no nameservers are specified on the zone, an automatic SERVFAIL is returned. When a forward zone&aposs nameserver returns a valid response to the DNS Cache, that response is cached and then returned to the requestor.
