Select the relationship of the Host to the appliance's Web cache from the Type list. Available options are:

• Sibling (local): If the peer is a sibling, then the appliance can only request Web objects already held
in the peer's cache. The peer cannot forward cache misses on behalf of the device. These peers are
not usually located in the direction of the appliance's route to the Internet.
• Parent (upstream): If the peer is a parent, then the appliance forwards requests to the peer. If the
peer does not have the requested Web object, it forwards the request on behalf of the appliance. These
peers are usually located in the direction of the appliances's route to the Internet.
Enter the port number for the cache to listen for proxy requests in the HTTP Port field, or accept the

Configuring ICAP client for Web Cache

The ICAP client of the appliance allows you to use a third-party ICAP server as an intermediary between
incoming traffic from the Web and LAN PCs browsing the Web. Outgoing Web requests or incoming Web
traffic is passed off to the ICAP server for processing before being returned to the requesting LAN PC. The
ICAP server can process outgoing Web requests from a LAN PC using a REQMOD service, or incoming Web
traffic from an external Web server using a RESPMOD service. A typical function of a REQMOD service
would be URL filtering. A typical function of a RESPMOD service would be virus scanning.
From the Network Setup menu, click Web Cache, select the Advanced tab, and then select the ICAP
