In a chaining proxy environment, how can downstream proxy administrative download traffic (such as WebFilter, CachePulse, Appliance Certificate Request, License Key Automatic Installation, et c.) be forced to go direct to the internet without being forwarded to an upstream Symantec ProxySG or Advanced Secure Gateway (ASG)?
The prerequisite is that the downstream ProxySG and ASG must be able to perform DNS lookup directly towards external Symantec domains.
