Parameter
ssl/server_cache_size
Short text
Max. number of session in the SSL server cache
Parameter Description
With this parameter, you can specify the maximum size of the cache for SSL server sessions. If an SSL server session can be negotiated successfully with the client, it is stored in the cache with the result that further accesses with the same client can take place with a shorter and more efficient authentication (provided the client controls the SSL session caching on the client side).
The duration for which a session can be reused in the cache is restricted. At regular intervals (1/4 of the session lifetime) sessions are deleted from the cache that have exceeded their life. When the cache’s upper limit is reached the system first tries to delete all sessions that have exceeded their life. A displacement according to LRU strategy (last recently uses) is applied so that a new session can be accommodated in the cache.
The life of a server session can be changed with profile parameter “ssl/server_cache_lifetime”.
