Configure an HTTP service
On the NetScaler appliance, a service represents a physical server on the network. In the transparent cache redirection configuration, the service represents the cache server. Cacheable requests are sent by the cache redirection virtual server to the load balancing virtual server, which in turn forwards each request to the correct service, which passes it on to the cache server.
Configure an HTTP service by using the CLI
At the command prompt, type the following commands to create an HTTP service and verify the configuration:
- add service <name> <IP> <serviceType> <port> -cacheType <cacheType>
- show service [<name>]

Example:
> add service Service-HTTP-1 10.102.29.40 HTTP 80 -cacheType TRANSPARENT
Done
> show service Service-HTTP-1
