This repository contains the configuration for our HAProxy load balancer.
The configuration includes a frontend named http_front that listens on port 80 and a backend named http_back that uses round-robin load balancing.
The configuration also includes rate limiting. Each client IP is limited to 10 requests per 10 seconds. If a client exceeds this limit, the server responds with a 429 status code.
haproxy.cfg: This is the main configuration file for HAProxy.
The backend servers are:
backend1backend2
Each server is checked for availability.
To use this configuration, replace backend1 and backend2 with the addresses of your actual backend servers, then load the configuration into HAProxy.
You can test the rate limiting by sending more than 10 requests in 10 seconds. If the rate limiting is working correctly, you should receive a 429 status code in response to the 11th and subsequent requests.
