By default, when we configure SSL Health Check for a Real-Server:
server real RS-web8 192.168.200.232
port ssl
port ssl keepalive
port ssl url “HEAD /”
port ssl status-code 200 200
The ADX will perform a simple SSL handshake. It doesn’t really check the content/status code. In order to force the ADX to check the content/status code, we would have to add this command globally:
(config)#no server use-simple-ssl-health-check
