Last published : Sep 30, 2026
The classic application workflow mirrors the NetScaler configuration model. It uses the same structure and the same names, such as load balancing virtual server, service and service group, and bindings.
Note:
Classic apps are disabled by default. To use classic apps, contact NetScaler® support to enable it for your account.

Sample configuration for a classic application

You are a NetScaler customer interested in using load balancing to evenly distribute network traffic and avoid overloading any back-end server. You also want to ensure that requests from a client are sent to the same back-end server.
Create the following entities:
  • Load balancing virtual server. Configure persistency settings on the virtual server.
  • HTTP service to bind to the virtual server.
Perform the following steps:
  1. Navigate to NetScaler Managed Apps > App Delivery > New Application.
  2. Click Switch to Classic Application.
  3. Type a name for the application and select an environment. Click Next.
  4. Select Load Balancing.
  5. Add a server. Click Add and specify a server name and the IP address of your back-end application server. Click Create.
    The server appears in the list of servers for the load balancing virtual server.
  6. Click Add in the Services section.
  7. Specify a service name and service type. Click Server Settings. Specify the server name that you created earlier and port as 80. Click Create.
    The service appears in the list of services for the load balancing virtual server.
  8. Add a load balancing virtual server. In the LB VServers section, click Add.
  9. Select Endpoint VServer and specify values for the following parameters:
    1. Name for the virtual server.
    2. Set Vserver Port to 80.
    3. Set Service Type to HTTP.
    4. Set Persistence Type to SOURCEIP.
  10. In Service Bindings, click Add.
  11. Type the name for the service that you created earlier and click Create.
    The service appears in the list of services bound to the load balancing virtual server.
  12. Click Create and then click Next. Provide the endpoint details. You have successfully created a virtual server. Click Submit.
    The application is listed on the Applications page.
  13. In the Actions column, click the three dots and select Deploy.
You have successfully deployed a classic application.
