 * I am using MaxCDN and recently got a 403 errors when any resource is requested
   from the CDN. If resource is requested directly then it is served correctly but
   not from CDN.
 * MaxCDN support asked me to whitelist few IP addresses. Can you please advise 
   how can I whitelist those IP addresses?
