If I understand correctly, limit_req only works if the same connection
is used for each request. My goal with limit_conn and limit_conn_zone
would be to prevent someone from circumventing limit_req by opening a
new connection for each request. Given that, why would my
limit_conn/limit_conn_zone config be any different from my
limit_req/limit_req_zone config?
