How do I configure a Group Policy so that Internet Explorer uses the PAC file?----
1) Log on to a server in the domain, and, with administrative permissions, open Start > Programs > Administrative Tools > Active Directory Users & Computers and expand your domain.
2) Right click the top-level domain or Organizational Unit where the policy should be applied, select Properties, and then select the Group Policy tab.
3)Create a 'GPO' and give it a meaningful name (Hosted Web Security, for example).
4)Edit the GPO from the following location: User configuration > Windows Settings > Internet Explorer Maintenance > Connection > Automatic Browser Configuration
5)Select Enable Automatic Configuration.
6) Under Auto-proxy URL (.JS, .JVS, or .PAC file), enter the path to the PAC file.
If you are running Websense Web Security Gateway Anywhere (hybrid) you will find the path for the PAC file located in the Web Security manager under Settings > Hybrid Configuration > User Access > Proxy Auto-Configuration (PAC). It will look something like this:
http://www.xyz.com:8082/proxy.pac?p=7)In Automatically configure every field, specify how often the web browser should query for the auto-configuration. For example, if you enter 240 minutes, every 4 hours the web browser checks for an updated PAC file. If you leave this field blank or set it to "0" the web browser is only configured when it is started.
