Enabling session ID caching

System Administration
Pertains to Windows platform

Cached session IDs enable a client and server to communicate with a shortened handshake.

To enable session ID caching on Windows platforms:

  1. Set the timeout value that applies to the session ID cache to a value greater than 0. Specify the SSLV2Timeout directive with valid values between 0 and 100, and the SSLV3Timeout directive with valid values between 0 and 86400. These values appear in seconds.
  2. Save the configuration file and restart the server.
System Administration
Pertains to UNIX platform

 

To enable session ID caching on UNIX platforms:

  1. Accept the default, or specify the SSLCacheEnable directive in the configuration file outside of a virtual host stanza.
  2. Assign a name to the port for the session ID cache, by specifying the SSLCachePortFilename, if the default name in the <server-root>/logs directory appears unacceptable.
  3. Set the timeout value that applies to the session ID cache. Specify the SSLV2Timeout directive with valid values between 0 and 100, and the SSLV3Timeout directive with valid values between 0 and 86400. These values appear in seconds.
  4. Decide whether to log caching errors. To enable logging of errors that can occur during session ID caching, or retrieval from the cache, specify the SSLCacheErrorLog directive in the configuration file outside of a virtual host stanza.
  5. Save the configuration file and restart the server.
