do you mean
a) send each request to both?
b) send each request to one or the other (like load balancing)

a) is not possible, simply because of the basics of proxying and http 
(there would be 2 http responses mixed into 1 connection)
b) can be done with 1 / location but adding another address to the 
upstream block:

|upstream backend {
     server   <ip address>
|||     server   <ip address>|

|server {
     location / {
         proxy_passhttp://backend  <http://original_upstream>;
