something about rrl

[陈超]

Dear developers,

I've recently encountered a problem with the response rate limit of bind-9.9.5.

That is,after I configured RRL and started named,I noticed for those queries,BIND9 would do recursion first,and check the rate limit to decide whether it should send a response or not,later.

Could you please tell me why RRL was applied in such a manner?If I really need to modify the BIND9 implementation to drop all those abused queries before recursions take place,can I just go ahead,without causing potential troubles?Is it risky?

Any kind of advice will be appreciated.Thank you.

Regards, 


Chao Chen
