Inconsistent Connection Handling in Traefik for Multiple Requests: Seeking One Connection Per Request Configuration

Traefik Traefik v2
, ,

I tried using RateLimit but since the connections don't follow a pattern it didn't work in my tests.

Example with default burst 1 and default period 1:

in the file dynamic-traefik.yaml I configured:

http:
  routers:
	rt-apache-websecure:
      entrypoints: websecure
      rule: HostRegexp(`{host:.+}`) && PathPrefix(`/`)
      service: srv-apache-web
      middlewares:
        - ratelimit-asd
  middlewares:
    ratelimit-asd:
      rateLimit:
        average: 3
        #burst: 3
        #period: 1s
  services:
    srv-apache-web:
      loadBalancer:
        servers:
		  - url: '{{env "APACHE_HOSTNAME"}}'

I made 3 requests in the same second

What I understood from the documentation is that average is divided by period and burst is the maximum volume. Therefore, 3(average) / 1(period) = 3 + 1(burst) = 4 requests within 1 second
