Server Name Indication - SNI

Since Payara Server and 5.182

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 SNI 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.
