I'm in the process of developing a REST API (apache now, but likely nginx when it goes live. The reason I'm considering nginx is for its ability to handle concurrent connections, and for built-in rate limiting. Does anyone have advice on rate-limiting requests on Apache (e.g. mod_evasive) vs nginx? The idea would be to limit users to a certain number of requests per IP per hour, and return a 503 over that limit.
