Create a load balancing virtual server

Last published : Sep 24, 2026
The cache redirection virtual server on the NetScaler appliance can send requests to either a cache server farm, if the request is cacheable, or to the origin server farm if the request is not cacheable.
Each cache server is represented on the appliance by a service, which is bound to a load balancing virtual server that receives requests from the cache redirection virtual server and forwards those requests to the servers.
For details on configuring load balancing virtual servers and other configuration options, see Load Balancing.
