95 There could be several <literal>limit_req</literal> directives.
96 For example, the following configuration will limit the processing rate
97 of requests coming from a single IP address and, at the same time,
98 the request processing rate by the virtual server:
99 <example>
100 limit_req_zone $binary_remote_addr zone=perip:10m rate=1r/s;
101 limit_req_zone $server_name zone=perserver:10m rate=10r/s;

103 server {
104 ...
105 limit_req zone=perip burst=5 nodelay;
