I want to limit requests to 1 per second for each user, counting a bot that makes requests from multiple ips as a single user. Does this make sense:

map $http_user_agent $single_user {
default $binary_remote_addr;
~PaperLiBot 1;
}

limit_req_zone $single_user zone=one:10m rate=1r/s;

...

limit_req zone=one burst=2;



Thanks

Dave
