Recommended approach is to export a variable with the appropriate
value, and use
proxy_set_header X-Your-Header $your_variable;
in the configuration.
For example, nginx itself uses this approach with X-Forwarded-For,
see the $proxy_add_x_forwarded_for variable description here:
http://nginx.org/en/docs/http/ngx_http_proxy_module.html#var_proxy_add_x_forwarded_for
