The Cache Server is responsible for handling all viewing requests from the WCS. The Cache Server checks whether or not it can fulfill the request with a cached report page. If it cannot, it passes the request along to the Page Server. The Page Server runs the report and returns the results to the Cache Server. The Cache Server then caches the information and returns the data to the WCS. By storing report pages in a cache, Crystal Enterprise avoids accessing the database each and every time a report is requested.
If you are running multiple Page Servers for a single Cache Server, the Cache Server automatically balances the processing load across Page Servers. For more information, see Modifying Cache Server performance settings.
