It was some time since I checked this last, but I think that 
when you use a proxy the browser will only query the dns for the 
proxy address (if needed, you can specify the proxy as 1.2.3.4).
It is actually the proxy that will do the dns lookups, since it
is the proxy that does the connecting to the real server.

There is a reason rabbit comes with the dnsjava library.

Rabbits support for client-rabbit connection pipelining is good. 

The support for rabbit-server pipelining is not so good, the big
problem is deciding when to use it and then we have the added
complexity of resends if pipelining fails.
