Using the answer at
https://serverfault.com/questions/597671/load-balancing-in-nginx-with-redirect-rather-than-proxy
as a basis, why not set $loc_redirect to the upstream host name, and then

|location / { |||return 302 $scheme://$loc_redirect$request_uri;| }|

( although negating the stickiness of the upstream redirect may have the
odd unwanted site effect ).
