Extract port number from URL and reverse proxy with Nginx

Question

I would like to setup my Nginx server so

/app/portnum

type URLs are reverse proxied to

localhost:portnum

E.g.

/app/1234

would be reverse proxied to

localhost:1234

can you URL's be longer, something like /app/port/some/extra/uri ? — Mohammad AbuShady

This may be helpful:

server {
    listen        80;
    server_name       test1.test.com;

    location ~ ^/app/(.*)$ {
        proxy_pass       http://192.168.154.102:$1;
    }
}

Notice: If you visit test1.test.com/app/8081, nginx will pass the request to http://192.168.154.102:8081/app/8081.

Ah, managed to work it out... I had to use re-write as well. I couldnt find the documentation anywhere which showed you could use regex groups in the location command. Thx
