I want to limit the connections used by nginx using CLI.

I know that we can set worker connections to different values in nginx conf file. But no of worker connections will include not only the connections to the host. It also includes proxy connections too.

If I want to give user flexibility to limit the connections, user will not know about proxy connections.

Is there any flexibility in nginx source code to know whether the connection established by nginx is to the proxy server or host connections ?

Can you please help me with this ?

Let me know if more information is needed.
