Web Agent Cache

The Web Agent stores user session and resource information in cache memory. This technique improves the Web Agent efficiency because the Web Agent does not have to retrieve information from the Policy Server each time a user requests access.

By configuring the cache settings, you can manage how this information is stored. The size of the cache is measured by the number of cache entries. The total number of entries in each cache cannot exceed the maximum cache size specified.

Note: You have to restart the Web Server for changes in the Web Agent cache settings to take effect.

The following guidelines apply to cache management:

• When a cache is full, new entries replace the least recently used entries.
• For the resource cache, entries are removed when the value of the ResourceCacheTimeout parameter is reached.
• For the user session cache, entries are removed based on the session timeout values that you set for each realm.

SiteMinder empties cached resource information when you modify a policy. You can also empty the user and resource caches manually from the Administrative UI.

Note: For more information, see the Policy Server documentation.
