3Com recommends that you configure the client machine that you use to 
manage the Webcache so that it does not use the Webcache as a proxy 
server. In Internet Explorer, select Tools -> Internet Options -> 
Connections -> LAN Settings and disable Use a Proxy Server. In Netscape, 
select Edit -> Preferences -> Advanced -> Proxies and select Direct 
Connection to the Internet.

You can use a Proxy Auto Configuration (PAC) file to configure the Web 
browser on each client machine. PAC files allow you to create 
configuration rules that determine how the Web browser operates when 
the Webcache is being deployed as a Proxy cache. The PAC file can be 
stored either on the Webcache or a network server, and the Web browser 
is set to read the PAC file when it is opened.

The main disadvantage of PAC files is that the PAC file is read once when 
the Web browser is first opened, and then executed within the browser 
for every object within every Web page visited. This can cause a perceived 
response time degradation, although the performance degradation is 
likely to be small.
