Oracle iPlanet Web Proxy Server 4.0.14 Performance Tuning, Sizing, and Scaling Guide

Tuning the ACL Cache

The Proxy server maintains an ACL Cache that maps between URLs and ACL Lists. The ACL cache improves performance by avoiding the need to build the ACL list applicable to a particular URL for each access.

However, the sheer number of URLs accessed through a Proxy server can cause the ACL Cache to grow to huge sizes. The magnus.conf directive called "ACLCacheMax" can be used to restrict the maximum number of entries in the ACL Cache.
