Does this proxy enable nginx session affinity? From looking at the nginx.tmpl file, it would appear not. It seems that this would be beneficial to include. When I release a new version of our website, I spin up containers with the new version and then stop containers with the old version. During this process, it's possible for a user to grab, for instance, the new javascript file but the old css file. By enabling session affinity, it would ensure that users that started out on the old version stay on the old version until the switch is complete. Is there anything that makes this possibility unrealistic?
