This application will expose two APIs:

/: This API will return a simple "Hello, world!" message. However, it will be rate limited based on the source IP Address. /rate_limit: This API can be used to get and set the rate limit. The GET method will return the current rate limit settings, while the POST method can be used to update the rate limit settings. To modify the rate using the GET and POST methods, we can send the following requests:

GET the health check link

curl http://localhost/flask-health-check

GET the browser info

open this link in the browser http://localhost/info

GET the current rate limit settings

curl http://localhost/rate_limit

POST a new rate limit setting

curl -X POST http://localhost/rate_limit
-H "Content-Type: application/json"
-d '{ "limit": 20 }' We can also test the rate limiting feature by sending multiple requests to the / API in a short period of time. If we exceed the rate limit, we will receive a 429 Too Many Requests response.
