i cant use limit_conn_zone

[farukest]

First of all i should say , my english not so good... And now my website is
underattack. I have to limit.
I'm using WT-NMP to use nginx php and mysql so i should use some code in
nginx.conf. E.g I'm using "limit_rate 700k" . But i dont understand what
should i do, Please give me more information.. or example. Thank you for
your patience :)
