Hi,

I have defined my backends in fastly.toml as:

[local_server]
  [local_server.backends]
    [local_server.backends.my-backend]
      url = "https://my-backend.app"

Now, I would like to fetch from the site without having to repeat the host:

fetch("/path/", { backend: 'my-backend' })

When I try this locally, I am getting empty string without any failure.

fetch("https://my-backend.app/path/", { backend: 'my-backend' })

This works correctly, however it duplicates the backend already stated in fastly.toml. What I need is to separate the configurations from the script - this unfortunately disallows me that.

Basically I would like to achieve something like this:

fetch(backends.my-backend.host + "/path/", { backend: 'my-backend' })

  For future reference for the community, this is resolved with:

      [local_server.backends.my-backend]
        url = "https://my-backend.app"
        override_host = "my-backend.app"
