54 CHAPTER 7: CONFIGURING CACHE REDIRECTION

Cache Redirection

Configuration

Example

Figure 13 illustrates a sample network configuration for cache

redirection. This example displays how cache redirection works.

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.
