Configure access to a source: URL list

To transfer data using a URL list, ensure that the following requirements are met:

• The URL list is publicly accessible from a URL beginning with either http or https.

• Each URL you specify is publicly accessible.

  For example, in Cloud Storage, you can share an object publicly and get a link to it.

• The server's robots.txt file allows access to each URL.

• The server hosting each object supports Range requests and returns a Content-Length header in each response.
