Hello,
Can somebody the http_req_rate counter still counts requests with the
following configuration even after all the traffic starts coming through
"error" backend only?
frontend all-requests 0.0.0.0:80
tcp-request content track-sc0 fe_id() table es_backend
use_backend error_429 if { sc_http_req_rate(0) gt 9 }
backend es_backend
stick-table size 1 expire 10s type integer store http_req_rate(10s)
backend error_429
mode http
errorfile 429 /etc/haproxy/errors/429rate.http
I expect http_req_rate to be decreased once the traffic goes to another
backend (error_429 in my case). Am I missing something and how it can be
achieved?
Any advice appreciated.
Kind regards,
