I have the future questions about RRL that:

#1 what's the meanings of responses-per-second and window in the config?
#2 under which condition RRL rejects the query, and under which 
condition it truncates the response?
#3 how to enable the log items for RRL? for example, I want to check 
what IP and what domains are influenced by RRL.

Thanks again.
