The PortalCache functionality currently relies on the JCS caching system.
The default JCS configuration file is located in
tomcat/webapps/Portal.Node/WEB-INF/defaultconfig/cache.ccf
.
If you want to customize the cache configuration you can copy this file to
${com.gentics.portalnode.confpath}
/cache.ccf
and modify it.
Further information on how to configure the cache is available at the official JCS Website. If your heart is set on another caching system you'll be happy to hear that our PortalCache API is soon to come.
The list of available cache regions including description and reasonable default values can be found in the default configuration file cache.ccf
