Access Gateway and SNI support
Introduction
Server Name Indication (SNI) is an extension to the Transport Layer Security (TLS) protocol by which a client can mention which hostname it is attempting to connect to at the start of the TLS handshaking process. This enables the server to select the correct virtual domain and corresponding TLS certificate at the very beginning of the process of establishing secure communication with the client.
The purpose of this document is to help users enabling SNI and getting benefits of it in secure TLS communication of Access Gateway (AG) (pre NAM 5.0). There are two such channels available at AG.
- Between browser and AG.
- Between AG and backend webserver.
