hey will

i dont know exactly how the appspot works but it seems that google uses
virtual domains on the same ip and response only to requests of domains
that are hosted on appspot.

what you are doing with a cache_peer is throwing the requested domain to
the ip of the cache_peer.

so the request that google server "mysite.appspot.com" gets is a request
for "my.public.domain.name" and since google is not hosting it the basic
rule is to redirect into google.com

to make it work change the http_port the option to
"defaultsite=mysite.appspot.com" and add "no-vhost"

on the http_access i'm not sure but i think you should add also the
"mysite.appspot.com" domain to the allowed such as:

acl gae dstdomain my.public.domain.name mysite.appspot.com

it works like a charm!
