54CHAPTER 7: CONFIGURING CACHE REDIRECTION
Cache Redirection Figure 13 illustrates a sample network configuration for cache
Configuration redirection. This example displays how cache redirection works.
Example
A request is entered into the browser, for example,
http://www.3Com.com. The browser then sends the request to the Server
Load Balancer.
The Server Load Balancer looks at the protocol and determines that it is the HTTP protocol and forwards the request to the cache server.
Upon receipt of the request, the cache server determines whether it has a local copy of the requested page. If not, the cache server sends its own request to www.3Com.com. When www.3Com.com responds to the cache server, the cache server forwards the response to the client, and if permitted, makes a local copy.
