Hi,
i want to configure a rate limit (say 100 http req/sec) for each backend
server like this:
listen front
bind :80
balance leastconn
server srv1 127.0.0.1:8000 limit 100
server srv2 127.0.0.2:8000 limit 100
As far i can see rate limiting is only supported for frontends [1].
However,a long time ago, someone asked about the same question [2]. The
proposed solution was a multi tier load balancing having an extra proxy
per backend server, like this:
listen front
bind :80
balance leastconn
server srv1 127.0.0.1:8000 maxconn 100 track back1/srv
server srv2 127.0.0.2:8000 maxconn 100 track back2/srv
listen back1
bind 127.0.0.1:8000
rate-limit 10
server srv 192.168.0.1:80 check
listen back2
bind 127.0.0.2:8000
rate-limit 10
server srv 192.168.0.2:80 check
Is there a better (new) way to do that? The old thread mentioned, its on
the roadmap for 1.6.
Cheers Stephan
