I think this can work.
upstream app {
server 127.0.0.1:8888 weight=5;
server aaa.app.com weight=95;
}
upstream appb {
server bbb.app.com;
}
server {
listen 80;
server_name www.app.com
location / {
proxy_pass http://app;
}
}
server {
listen 127.0.0.1:8888;
location / {
rewrite ^ /beta-app/$request_uri break;
proxy_pass http://appb;
}
}
