Maintain client connection for multiple client requests

August 1, 2023

You can set the client keep-alive parameter to configure an HTTP or SSL service to keep a client connection to a website open across multiple client requests. If client keep-alive is enabled, even when the load balanced Web server closes a connection, the NetScaler appliance keeps the connection between the client and itself open. This setting allows services to serve multiple client requests on a single client connection.

If you do not enable this setting, the client opens a new connection for every request that it sends to the website. The client keep-alive setting saves the packet round trip time required to establish and close connections. This setting also reduces the time to complete each transaction. Client keep-alive can be enabled only on HTTP or SSL service types.

Client keep-alive set at the service level takes precedence over the global client keep-alive setting. For more information about client keep-alive, see Client Keep-Alive.

To enable the client keep-alive on a service by using the CLI

At the command prompt, type:

set service <name> -CKA <Value>
<!--NeedCopy-->

Example:

set service Service-HTTP-1 -CKA YES
<!--NeedCopy-->

To enable the client keep-alive on a service by using the GUI

Navigate to Traffic Management > Load Balancing > Services, and open a service.
In Advanced Settings, select Traffic Settings, and select Client Keep-Alive.
