Rate Limiting With nginx

This article explains how to use the nginx HttpLimitReqModule to limit the number of requests for a given session. This is useful, for example, if your site is hammered by a bot doing multiple requests per second and thus increasing your server load. With the HttpLimitReqModule you can define a rate limit, and if a visitor exceeds this rate, he will get a 503 error.
