You can manage what is gathered in the server's cache and fine-tune your Cache Refresh and Cache Agent settings to best use the cache. For example, you have the ability to specify that certain URLs' content be pre-loaded in the cache, regardless of whether those pages were in the cache previously. You also have the ability to specify whether the cache agent will follow links from the popular pages it preloads and also cache the content from those links. The linked pages can reside on the same host as the source page, or on other hosts.
