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.

[Linux][AIX][z/OS][HP-UX][Solaris]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.
