The SteelApp Traffic Manger version 10.0+ supports configuring an HTTPS health monitor that will send an SNI TLS extension to the back-end server.
For this HTTPS monitor to work properly, the Pool SSL configuration option 'ssl_server_name' must be enabled.
After creating the HTTPS monitor to attach to the Pool, you need to enable the Pool SSL configuration option by following these steps:
- Set the VS directing to this pool to: Discard
- Navigate to Services > Pools > Pool_Name > Edit > SSL > Server Authentication: ssl_server_name: yes
- Click Update
Note: SNI is only sent to the pool nodes when using the hostname rather than the IP address. For example, if the node in the pool is mywebnode.steelapp.local:443, then SNI will be sent. However, if the node is 18.104.22.168:443, then SNI will not be sent.
