The number of current cache entries and the maximum number of cache entries are both displayed. A single cache entry represents a single URI.
You can set the maximum number of cached entries by:
Entering a value in the Maximum # of Files field on the File Cache Configuration page under Preferences in the Server Manger
Creating or editing the MaxFiles parameter in the nsfc.conf file. For more information about this file, see the Sun Java System Web Server 6.1 SP7 Administrator’s Configuration File Reference.
