Hi Bert,

It works perfectly! Thank you for the commit.

I have another question. I want the limit the  queries per second. For  
this purpose i wrote;

newServer{address="", qps=5}

Then i test with DNS flood attack, and i assumed that the max answer  
query per second is 5. Bu it wasn't. What is the main purpose of qps  
limit? Is it for forwarding queries?

Thank you.

Best Regards
Burak Ozalp
