I know nginx (reverse proxy) can do this. FYI

I would be interested in this too. I have had a look a nginx before, but it was out of the scope of my knowledge . A tutorial from a guru out here could be very interesting.

This might be thé stupidiest suggestion ever, but, why not create a b4j server to receive thé "général" call and make it calk thé URL spécific page? À kind of "transparent redirect"

For ws, you need to set header "Upgrade" and "Connection". https://www.nginx.com/blog/websocket-nginx/

Config below may work.

### $ cat /etc/nginx/nginx.conf

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    # include       mime.types;
    # default_type  application/octet-stream;
    # sendfile        on;
    # keepalive_timeout  65;

    server {
        listen      80;
        server_name a.com;
        location / {
            proxy_set_header   X-Real-IP $remote_addr;
            proxy_set_header   Host      $http_host;
           
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
           
            proxy_pass         http://127.0.0.1:8081;
        }
     
    }

    server {
        listen       80;
        server_name b.com;
        location / {
            proxy_set_header   X-Real-IP $remote_addr;
            proxy_set_header   Host      $http_host;
           
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
           
            proxy_pass         http://127.0.0.1:8082;
        }
       
    }
}

        }
 
    }

I try your conf in VPS. It's OK.

As following, vps.jinyistudio.tw isn't OK but vps.jinyistudio.tw:8001 is OK when i connect from remote desktop .

vps.jinyistudio.tw works fine here. Close the browser / try to refresh the page F5
