Is your feature request related to a problem? Please describe.
I'm trying to use Traefik to host Homer behind a Reverse Proxy. The path I'm trying to use is 192.168.2.207/homer. However all .js includes are being done like this:
image

<link rel="stylesheet" href="./resources/index41a7d45b.css">

Describe the solution you'd like
A way to host homer on a path lower then the root of a webshite.

Describe alternatives you've considered
I tried all kinds of things with Traefik but haven't been able to resolve it. The only other option is trying to do something like homer.blah rather then blah/homer.

Additional context

i think you must use the SUBFOLDER enviroment variable in the docker compose file, i have the same issue and setting the variable like SUBFOLDER=/homer in the docker compose doesn't solve the issue

version: "3.8"
services:
  homer:
    image: b4bz/homer
    container_name: homer
    volumes:
      - ./data:/www/assets
    user: 1000:1000 # default
    environment:
      - INIT_ASSETS=1 # default
      - SUBFOLDER=/homer
      - PORT=80
    restart: unless-stopped
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.homer.rule=Host(`raspberry`) && Path(`/homer`)"
      - "traefik.http.routers.homer.entrypoints=web"
      - "traefik.http.services.homer.loadbalancer.server.port=80"
      - "traefik.http.routers.homer.middlewares=homer-prefix"
      - "traefik.http.middlewares.homer-prefix.stripprefix.prefixes=/homer"
      - "traefik.http.middlewares.homer-prefix.stripprefix.forceSlash=false"
    networks:
      - traefik
networks:
  traefik:
    external: true

I tried also without the last 3 labels but the problem persists:

- "traefik.http.routers.homer.middlewares=homer-prefix"
- "traefik.http.middlewares.homer-prefix.stripprefix.prefixes=/homer"
- "traefik.http.middlewares.homer-prefix.stripprefix.forceSlash=false"

I'm sure the proposed solution works, i.e. rewriting content or introducing another reverse proxy to rewrite the paths to reverse the first reverse proxy.

I can offer my own solution #694, however note that unlike the previously proposed solution, while avoiding rewrites, it requires building your own homer docker package to set the vite base url, e.g.:

$ docker build -t homer --build-arg SUBFOLDER=/bar . && docker run --rm -p 8080:8080 -e SUBFOLDER=/bar homer

Use SUBFOLDER as asset base to allow mounting homer at a different base path. ignatz/homer
