Server Name Indication, SNI for short, allows you to use multiple SSL certificates with the same IP address. When enabled, the server will look for a certificate in the configured keystore using a nickname that matches the host name requested.
SNI can be enabled by configuring a network listener. Existing network listeners can be configured from the admin console or with asadmin commands. The network listener configurations can be found in the admin console under Configurations → your-config → Network Config → Network Listeners.
From here, click on the SSL tab, and make sure that the SNI Support checkbox is ticked.
|For this to take effect, the network listener must have security enabled by providing a default keypair and certificate, and by checking the Security box on the HTTP tab.|
