Overview

This section of the Websense Technical Library provides information specific to integrating Websense® Web Filter or Web Security with Squid Web Proxy Cache. Refer to Web Filter or Web Security (software-based) as your primary source of installation instructions. Only additional or alternative steps required to integrate Web Filter or Web Security with Squid Web Proxy Cache are provided here.

When Websense software is integrated with Squid Web Proxy Cache, the following components are configured differently than in a stand-alone installation:

Websense Squid plug-in must be installed on each Squid Web Proxy Cache machine (Squid machine) to allow Squid Web Proxy Cache to communicate with Filtering Service.

Websense Network Agent is configured to manage only the Internet protocols not managed by Squid Web Proxy Cache (e.g., instant messaging, streaming media, peer-to-peer). Typically, Network Agent runs on a machine connected to a bi-directional span port (or mirror port) on a network switch processing the traffic to be monitored. Network Agent monitors the non-HTTP(S)/FTP traffic directed through the switch. You can install Network Agent on the same machine as Squid Web Proxy Cache. If you do so, a span port on a switch is not necessary for Network Agent to operate—it will be able to monitor the same traffic visible to the Squid machine.
