Are you sure its redirected? That doesn't sound right. In fact I dont see how it can do, if it was redirected the hostname would go missing, and the hostname (containing the appname) is needed to route the request to your application (rather than the thousends of other apps runnong on appspot)
There is a DNS CNAME, but its effectively an internal detail of how the DNS is routed. It's very common for sites to use CNAMEs to handle DNS - particully for routing requests via a CDN. It seems very odd that any whitelisting system would use an intermediate CNAME hostname for whitelisting. It should either use the original hostname (ie the hostname in the URL) or the final IP address. If the final IP you are out of luck, because Google uses many IPs for AppEngine. You need whitelisting on the original hostname.
