Configuring ICAP Service

Applies to:
  • Forcepoint URL Filtering, v8.5.x

ICAP Service behavior can be customized by modifying a configuration file called icap.conf, located in the bin directory (C:\Program Files\Websense\Web Security\bin, or /opt/Websense/bin/, by default) on the ICAP Service machine.

The icap.conf file can include the following parameters. Options marked with an asterisk appear in the file by default. The others can be added to the file if needed.
