cdn on subfolder instead of subdomain

[Snuupy]

Hi, I want the flags (or in the future, other media) to be displayed on the path https://adventurelog.domain.tld/media instead of https://cdn.adventurelog.domain.tld since it goes through the same reverse proxy on my self-hosted setup. I want to maintain a separation of concerns for my existing reverse proxy (which reverse proxies different self-hosted apps), and not add a volume mount to it. I don't really want to add another subdomain (cdn.domain.tld) for the sake of several (currently smol) images. This is also an example of a working nginx/swag reverse proxy config.

My current swag (nginx) config:

server {
    listen 443 ssl;
    listen [::]:443 ssl;

    server_name adventurelog.*;

    include /config/nginx/ssl.conf;

    client_max_body_size 0;

    location / {
        include /config/nginx/proxy.conf;
        include /config/nginx/resolver.conf;
        set $upstream_app adventurelog-web;
        set $upstream_port 3000;
        set $upstream_proto http;
        proxy_pass $upstream_proto://$upstream_app:$upstream_port;

    }

    location /media/ {
        include /config/nginx/proxy.conf;
        include /config/nginx/resolver.conf;
        set $upstream_app2 adventurelog-nginx;
        set $upstream_port2 80;
        set $upstream_proto2 http;
        proxy_pass $upstream_proto2://$upstream_app2:$upstream_port2;

    }
}

Excited to play with this app and play with it to plan my next trip! :)
