Session ID cache
IBM HTTP Server caches secure sockets layer (SSL) session IDs when Web clients establish secure connections with the Web server. Cached session IDs enable subsequent SSL session requests to use a shortened SSL handshake during session establishment. Session ID caching is enabled by default on all supported platforms.
The session ID cache is implemented as a daemon process named sidd. You will see this process running when IBM HTTP Server is started with SSL enabled.
In most cases, you will not need to take an additional configuration steps to effectively use SSL session ID caching in IBM HTTP Server.
