What is caching on-command?
Caching on-command enables an administrator to schedule batch updates to the cache. This includes: • the ability to preload documents or sites into the cache in anticipation of user demand • the ability to automatically refresh documents that already reside in the cache Administrators can schedule batch updates to take place at regular intervals and off-peak hours so network bandwidth is not tied up caching documents during periods of heavy network use. Caching on-command is more efficient than “active caching” because administrators have the ability to control batch updates. Administrators can check the proxy access logs to determine whether frequently accessed sites are actually desirable for caching. Plus, administrators don’t have to wait for usage patterns to develop to specify batch updates.
