Integrating Web Security using ICAP Service

Deployment and Installation Center | Web Security Solutions | Version 7.7.x

Websense ICAP Service makes it possible to integrate Websense Web Security solutions with third-party proxies and proxy-caches that support communication with ICAP servers.

Integration via ICAP affects the following Websense components:

Websense ICAP Service is installed with Filtering Service. It includes an ICAP server that enables third-party proxies to communicate with Filtering Service.

Websense Filtering Service interacts with ICAP Service and Network Agent to filtering Internet requests passed from the proxy via ICAP.

For installation instructions, see Installing Web Security to integrate with ICAP Service.

After installing Websense software, configure your proxy to communicate with Websense ICAP Service (see Configuring the proxy to communicate with ICAP Service).

The Websense service may also require configuration (see Configuring ICAP Service) if the default settings are not appropriate for your environment.

To be filtered by Websense software, a computer must access the Internet through the integrated proxy.

When the proxy receives an Internet request, it uses ICAP to query Websense ICAP Service to find out if the request should be blocked or permitted. ICAP Service queries Filtering Service, which checks the policy assigned to the client and either serves a block page or notifies the proxy to permit the request.
