Sun Java System Web Server 6.1 SP7 Performance Tuning, Sizing, and Scaling Guide


Set this directive to a number that determines the number of seconds before the cache entries expire. Each time an entry in the cache is referenced, its age is calculated and checked against ACLCacheLifetime. The entry is not used if its age is greater than or equal to the ACLCacheLifetime. The default value is 120 seconds. If this value is set to 0, the cache is turned off. If you use a large number for this value, you may need to restart Sun Java System Web Server when you make changes to the LDAP entries. For example, if this value is set to 120 seconds, Sun Java System Web Server might be out of sync with the LDAP server for as long as two minutes. If your LDAP is not likely to change often, use a large number.
