Upgrading the Squid plug-in

To upgrade the Squid plug-in, run the Web Security Linux installer on the Squid Web Proxy Cache machine and follow the onscreen instructions. For proper communication to be established with Squid Web Proxy Cache, upgrade Websense Filtering Service before upgrading the Squid plug-in.

When you upgrade a previous version of Websense Web Filter or Web Security integrated with Squid Web Proxy Cache, pre-existing Websense tags in the Squid Web Proxy Cache configuration file (squid.conf) are reset to default. A backup copy of the file with pre-upgrade settings can be found in the backup directory (/opt/Websense/backup/).

If you had custom values in place in this file before the upgrade, you can either manually edit the tags after upgrade or make the backup squid.conf file active in the system (See Squid documentation for more information).

The following tags in squid.conf are affected.

Squid v2.5: redirect_program, redirect_children and redirector_bypass

Squid v2.6: url_rewrite_program, url_rewrite_children and redirector_bypass
