Configure Hybrid FilteringFor Microsoft Internet Explorer 8 or 9, go to Tools > Internet Options and clickthe Connections tab. Click LAN Settings, and then mark Use automaticconfiguration script. Enter the PAC file URL in the Address field.For Mozilla Firefox 3.x, go to Tools > Options, click the Advanced icon, andthen select the Network tab. Under Connection, click Settings, and then selectAutomatic proxy configuration URL. Enter the PAC file URL in the blank field.The default PAC file is supplied by Websense, and comprises default settings from thehybrid service and any changes you make on the Hybrid Configuration pages. If youwant to customize the PAC file, create a directory named pac in the Websense ssdatadirectory (by default, \Program Files\Websense\Web Security\bin\ssdata\pac onWindows, or /opt/websense/bin/ssdata/pac on Linux). Then you have the followingoptions:To use your own PAC file, create a file named websense.pac and place it in theWebsense pac directory.To add a customized fragment to the default PAC file, place the JavaScriptfragment in a file named customfinal.pac, and put it in the Websense pacdirectory. This fragment is appended to the default PAC file, replacing the token_CUSTOMFINALPAC_.NoteThe customized websense.pac file must contain thefollowing function:function FindProxyForURL(url, host) {}If this function is not in the file, it will be rejected by thehybrid service.If either of these files exists in the pac directory, Sync Service detects it and sends thedata to the hybrid service. The file must be greater than 0KB and smaller than 50KBfor Sync Service to send it. Sync Service also detects when there is a newer version ofthe PAC file or fragment and updates the version on the hybrid service.The recommended state for custom PAC files is to set up a custom file or a customfragment, not both. If both files exist in the pac directory, we recommend you decidewhether a full customized PAC file or a customized fragment suits your needs better,and delete the other file from the directory.To stop using a customized PAC file or fragment, delete the file or fragment from thepac directory.The Hybrid Service page displays the type of PAC file you are using, and lists thedate and time that Sync Service last sent a customized file or fragment to the hybridservice (see Monitor communication with the hybrid service, page 241).If you are unfamiliar with PAC files, it is useful to search the Internet for basicinformation. Wikipedia has a good introductory article, and a good Web site for moreinformation and several example PAC files is http://www.findproxyforurl.com/.226 Websense Web Security Gateway Anywhere
