If "key" is "$binary_remote_addr", it will be the same for the same
client ip, and different for different client ips; the limits apply to
each individual value of client ip (strictly: to each individual value of
"key").

If "key" is (for example) "fixed", it will be the same for every
connection, and so the limits will apply for all connections.

Note: that limits concurrent connections, not requests.

http://nginx.org/r/limit_req_zone

Again, set "key" to something that is the same for all requests, and
the limit will apply to all requests.
