Figure 14 shows a small commercial Web site designed to provide efficient catalog browsing. All client requests pass through the firewall to a Dispatcher that routes the requests to a cluster of proxy servers with active caches that act as surrogate servers to the Web servers.

This arrangement reduces the network load on the Web servers and isolates them from direct contact with the Internet.
