Limit requests per IP on Nginx using HttpLimitZoneModule and HttpLimitReqModule except whitelist

– Make sure to check Nginx, PHP posts for information on Nginx and PHP setup and configuration.

Nginx offers two modules, HttpLimitReqModule and HttpLimitZoneModule, to limit simultaneous connections for the assigned session and the number of requests for a given session from one IP address. Basically these modules are built to protect the web server from possible DDos attacks; For example, this configuration limits remote clients to no more than 20 concurrently “open” connections per remote ip address:

    limit_conn_zone  $binary_remote_addr zone=concurrent:10m;
    limit_conn_log_level warn;
    limit_conn  concurrent  20;
