Forward to external URL

Hello. I hope, someone can help me. I try to forward my request through traefik with a dynamic file configuration:

  # Add the router
      entryPoints = ["web"]
      service = "service-foo"
      middlewares = ["middleware-replacepath"]
      rule = "Path(`/foo`)"

  # Add the middleware
      path = "/imghp"

  # Add the service
      passHostHeader = true
        url = ""

Now i call this url in my Browser (http://localhost/foo) and i expect to see google`s image site, but i get a 404 from google. It seems, that traefik first resolves the domain into the ip.

Google is only an example, i use an own external domain :slight_smile:
Is it not possible or is my configuration wrong?

Thanks in advance
