🛫 How to use it?

1. Place your image files into a directory mounted into the container (or accessible on host).
2. Start the app with Docker:

docker run -p 8080:8080 \
-e AUTH_SERVER_BASE_URL="http://your-auth-server.local/auth" \
-v $(pwd)/images:/app/static \
ghcr.io/tobiasz-gleba/image-hosting-with-forwarded-auth

Now you can:

GET http://localhost:8080/cats/image1.jpg

And it will:

• Forward request to: http://your-auth-server.local/auth/cats/image1.jpg
• If 200 OK → return cats/image1.png or .jpg or .jpeg
• If not → return 401 Unauthorized
