ICAP client
The SnapGear unit’s ICAP client allow you to use a third-party ICAP server as an
intermediary between LAN PCs browsing the web and/or traffic incoming from 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 may 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, and a typical function of
a RESPMOD service would be virus scanning.
Click Advanced then ICAP Client.
Check Enable ICAP functionality to enable the ICAP features of the SnapGear unit’s
web cache.
ICAP REQMOD server is the URL for an ICAP server's REQMOD service. This allows
an ICAP server to modify web transaction requests, i.e. to process as they are being
initially requested by the LAN PC, e.g. for URL filtering. It must begin with icap://, e.g.:
icap://192.168.0.10:1344/reqmod
