Hello.

I still don't really get the 'map' magic. This example does not work for me - bots still connect as often as they please. But your example gave me an idea. After some reading and fiddling I managed to solve the riddle this way:

http {
limit_req_zone $limit_bots zone=bots:10m rate=1r/m;
server {
location / {
set $bot '';
if ($http_user_agent ~* (google|bing|yandex|msnbot) ) {set $limit_bots $binary_remote_addr;}
limit_req zone=bots burst=5 nodelay;
}
}
}

I will continue reading docs and hope to figure everything out eventually. By now it works for me.

Thank you for your help!
