LocalLB::DNSCache::set_randomize_query_name_case_state

Introduced : BIG-IP_v11.3.0
Sets whether to randomly vary the case of letters in domain names queried for a set of DNS caches. If disabled, the resolver will not vary the case of letters in domain names queried. The DNS standards require that nameservers treat query names case-insensitively. Domain names with the same letter, regardless of the case, should resolve to the same IP address. On the other hand, for the response, nameservers should preserve the original case that appeared in the request. This technique will help to reduce the risk of cache poisioning.
