I am trying to read metadata from a file over https on a public web

Without authentication gdalinfo works correctly. However I need to use
authentication, but so far I didn't manage to do that.

However gdalinfo is still not working and I am wondering If I am doing
something wrong or if there is any other option to include in the
command.

The error I am getting is:

gdalinfo /vsicurl/https://[a-public-site-requiring-credentials]/[my-file-h5]

ERROR 1: Range downloading not supported by this server!
gdalinfo failed - unable to open '/vsicurl/https://l....h5'

Hmm. Can you use gdalinfo /vsicurl *on this site* without autjentication ?

"Range downloading not supported" suggests that the server can only
give you the whole file, not just the bits with the metadata.
I don't think this is about authentication at all.
