The Server Name directive is needed only for a farm of multiple Cisco SPSs; it represents either the virtual IP (VIP) address of the farm if the farm resides behind a load balancer, or the DNS SRV record for the farm. For example, if proxy1.cisco.com and proxy2.cisco.com are members of the same farm, you can configure a server name such as farm.cisco.com to represent both proxies. For redundancy, endpoints can direct their requests and responses to farm.cisco.com so that either member of the farm can handle them during normal operation and in the event of a proxy failure.

• SRV Lookups For FQDN Only―Enables SRV DNS lookups only on FQDN hosts (an FQDN is a fully qualified domain name). A Request-URIs URL whose host portion is not an IP address and has a period is considered an FQDN. The system normally performs SRV DNS lookup for any host portion that does not contain a target port. Default is Off.
