The problem is that with VHS requests,
the list-buckets operation does not work
because the request is filtered on
list-objects-v1. Since list-buckets can
also have query parameters, in the end it
is necessary to distinguish list-buckets
from list-objects-v1 only by the presence
of the bucket name in the URL (provided
that the request is in VHS style).
