1.1 Overview
Hypertext transfer protocol (HTTP) is one of the most widely used approaches to
access the Internet. Ethernet switch provides Web cache redirection function, which
helps relieve the pressure on the links connecting to WANs and improve the speed to
access the Internet. The following figure shows an implementation of Web cache
redirection.

Figure 1-1 Web cache redirection
As shown in the figure, PC is one of the users in the LAN connected to the switch, and
Web cache is the server that stores the Internet information often browsed by the users
in the LAN. When Web cache redirection is enabled on the switch, the access to the
Internet via HTTP is redirected to Web cache. If the desired contents are in the Web
cache, the Web cache directly forwards them to users, thus eliminating the access to
the Internet. If the cache does not have the information, the users will log onto the
Internet to obtain information.
