Caching session IDs

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

It is necessary to cache the session IDs in a server-wide cache space. This is being done 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.
