I am trying to achieve rate limiting using HAProxy. I am trying to 
follow the "Limiting the connection rate per user" approach. I am able 
to achieve this by the below configuration. But facing one problem, 
that is, i am not able to send a custom error code once the rate limit 
is reached. For example if i reached the rate limit i want to send 
HTTP error code 429. In this case the proxy is simply rejecting the 
incoming call and users are getting http status code as 0.




"tcp-request connection reject" rejects the connection, so there is no 
status code in this case.  If you want to send a 403 replace it with 
"http-request deny if ..." instead.


If you want to respond with HTTP 429 make a backend with no backend 
servers (so that all requests will get a 503) and set a custom 503 error 
page, editing the headers at the top of the file so that the response 
code is 429 (or whatever other code/message/etc you desire).

Please let me know how can i do this

frontend localnodes

|bind *:80 mode http default_backend nodes stick-table type ip size 
100k expire 30s store conn_rate(5s) tcp-request connection reject if { 
src_conn_rate ge 60 } tcp-request connection track-sc1 src |


backend nodes

|cookie MYSRV insert indirect nocache server srv1 :80 check 
cookie srv1 maxconn 500 |

Hello, I am receiving a pop up states from Microsoft edge and HA Proxy 
statistics asking for my sign in. Is this you?  what is this for? And how do I 
eliminate it?
Thank You,
