Hi,
I have setup this module https://bitbucket.org/nginx-goodies/nginx-sticky-module-ng/src/master/ to have an upstream server persistance using cookies,
I compiled nginx 1.18.0 with this module suscessfully.

Here is my loadbalancer configuration:

/etc/nginx/conf.d/loadbalance.conf

proxy_cache_path /path/to_cache/dir keys_zone=backcache:10m;

upstream backendServers {
server IP1:81;
server IP2:81;
sticky name=mysticky expire=10860 path=/;
}


server {
listen IP3:80;
server_name example.com;

location / {
return 301 https://$server_name$request_uri;
}
}

server {
listen IP3:443 ssl;
server_name example.com;

location / {
proxy_pass https://backendServers;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
...
}
}

backend servers are running iis linked with coldfusion (tomcat).
The sticky seems not working: when I stop a web site on server 1, nginx continue to send requests to that
server. The loadbalance occures only when I clear the browser cache, or reboot server 1.
The cookie is set (name, expiration,...) but nginx is "sticked" to the down server.

Is someone here who has tested thi s module (https://bitbucket.org/nginx-goodies/nginx-sticky-module-ng/src/master/) with recente nginx version
If yes, is it working ? ciuld you share your experience ?

Thanks
