WPAD can be used with Content Gateway, but is not an option with hybrid web filtering. WPAD uses two methods to publish the location of the proxy configuration file the Dynamic Host Configuration Protocol DHCP, and the Domain Name System DNS. A web browser using this method sends a query to the local DHCP server and if it does not send back the desired information, uses DNS. For more information about using WPAD with Content Gateway, see Using WPAD. Specifying the PAC location The exact mechanism for configuring a browser to locate and use a PAC file depends on the browser and network environment. If you are using Microsoft Active Directory and Internet Explorer, you can automate the process via a Group Policy Object GPO. This is the recommended, best practice.
