How to get directory listing ?

I am trying to use a gohttpserver as a remote source for rclone. [https://rclone.org/http/] requires directory listing returned in index.html. Is there a way to get remote directory listing ?

Start by reading the repository's HTTP static file server behavior and the rclone HTTP directory-listing requirement described in the issue. Determine whether remote directories can expose an index.html listing, and document or implement a clear approach whose result is consumable by rclone.
