'NGINX - Return backend server name in the response header
I am running a nginx server and using it as reverse proxy (using proxy pass). See below image for my setup.
In the setup, user hits NGINX. NGINX based on proxy pass hits another backend server to get response. This backend server can be load balanced in some cases. In a load balanced scenario, system will hit one of the backend server to get response.
What I want: When response is returned from backend server, I want to include the backend server name in the response header. How can I get the desired output? Do I also need to make changes in backend servers\application? Application on backend servers are running on different web servers (IIS, Tomcat, NGINX etc)
