Note 
Policy-based routing (PBR) uses access control lists (ACL) to identify and redirect flows. In a PBR deployment, all of the configuration is done on the router and there is no corresponding Content Gateway configuration. PBR deployments have to redirect traffic returning from origin servers from port 80 and 443 to Content Gateway.
