Apache server is behind a physical loadbalancer et it uses an https connection between. The loadbalance break the https en create a new https connexion with apache.
So it's always the same client that makes calls to the apache server.
But in my serveur status I see that the cache is actived but SSL session are never retrieves from cache it always miss.
Why ? Because I imagine that configuration with the loadbalance will make only one SSL sesssion reused in each connection.
There is some hit but the cache seems not be used
