Limit_conn_zone applied to Proxy_Pass (outgoing requests)

Server NGINX
1

Hello!

I have an nginx reverse proxy it has a series of filters against DDoS
attacks.

As a last resort I need to make sure that I NEVER send more than x
concurrent requests to the backend server (Proxy_pass)

Is it possible to apply limit_conn_zone for outgoing requests? If so
could
i have an example? Thanks.

Alex

Any reason this needs to be applied specifically to /outgoing/
connections? Is the default behavior applied to the proxy not
sufficient?

Look at the “max_conn” parameter of the “server” directive
in the “upstream” block:

Note that it’s part of the commercial version of nginx.
