Hello,

I have setup nginx 1.9.3 as a reverse proxy [1] with a rate limitation  
per  
server [2]. The rate limitation does not work on this scenario. The rate  
request limitation works well if I use nginx as a normal webserver (for  
example to serve the default welcome page).

I have attached my configuration files (listen on 80 and redirect to  
another webserver running lighttpd).

[1] [Module ngx\_http\_proxy\_module](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_pass)  
[2] [Module ngx\_http\_limit\_req\_module](http://nginx.org/en/docs/http/ngx_http_limit_req_module.html)

Best Regards,  
poiuytrez

PS : You can run it in a docker using the following commands if you  
need:

docker run --rm --name nginx -p 8082:80 -v  
/yourdir/nginx.conf:/etc/nginx/nginx.conf:ro -v  
/yourdir/default.conf:/etc/nginx/conf.d/default.conf --link  
backend:backend  
nginx

docker run --rm --name backend -p 8081:80 jprjr/lighttpd

Go to [http://localhost:8082/](http://localhost:8082/) in your web browser.

Hello guys,

Is it a bug, something not implemented or a mistake on my side?

Best,

There is no “limit\_req” directive anywhere in your config, so it’s  
not a surprise rate limiting does not work.

You have to configure both “limit\_req\_zone” (to configure shared  
memory zone to store states) and “limit\_req” (to configure  
particular limits in particular locations), see  
details here:

Hello Maxim,

You are completely right. I must have been completely tired to miss it.

Thank you,  
Guillaume
