I must clarify, as I'm not positive what you heard is what I meant to say.
Perhaps we are speaking a different protocol ;) My comment is not about
URL validity, just about usefulness. Lets imagine a server X which
supports... everything. And say client software A supports only the
"smb://" style and client software B only does "cifs://". Now off on
server Y is a document with an embedded URL linking to a SMB/CIFS file back
on server X. What form should said URL take? Either form will shut out
some users, preventing them from accessing a server resource even though
client & server could have communicated fine.
That is what I meant with case 1) "they have a different client". Feel
free to ignore case 2) "the server has changed" until we have case 1)
