Lightboard Lessons: TLS Server Name Indication
Server Name Indication (SNI) is an extension to the TLS protocol that allows the client to include the requested hostname in the first message of the SSL handshake (Client Hello). Prior to the introduction of SNI, the client could not easily establish secure connections to multiple servers hosted on a single IP address. Because SNI lets the client identify the intended secure server during the initial part of the TLS handshake, it allows the server to host more than one secure website on a single IP address. In this Lightboard Lesson video, John explains the details of SNI and how you can configure it on your BIG-IP. Enjoy!
