I haven't tried it with varnish, but I think it should work if you  
use "Expires: ..." rather than "Cache-Control: max-age=..." to  
specify the TTL.

I'm curious why you want to use that setup though.  It seems like you  
are just introducing an extra single point of failure and wasting a  
lot of memory.    There are at least a couple of different setups  
that seems more reasonable.    What are you trying to accomplish?
