The SRV record
provides information about the services available on the NetScaler appliance.
An SRV record contains the following information: name of the service and the
protocol, domain name, TTL, DNS class, priority of the target, weight of
records with the same priority, port of the service, and host name of the
service. The NetScaler chooses the SRV record that has the lowest priority
setting first. If a service has multiple SRV records with the same priority,
clients use the weight field to determine which host to use.
