Caching session IDs

To offset the expense of SSL handshakes between a client and server, cache session IDs. Cached session IDs enable a client and server to communicate with a shortened handshake. The session ID cache runs as a separate process.

Cache the session IDs in a server-wide cache space, through a session ID cache daemon (SIDD). Each Apache server process communicates with SIDD to get and set session ID information.

You can set timeout values that indicate how long entries last in the session ID cache.
