It is a non-documented feature that the license file (named license.config) may be renamed [server-name]license.config (e.g. appserv3license.config) in order to distinguish different license files in a shared environment.
Is this a good solution even if there is only one license file in the web directory?
ElektroPost can (of course) not name the file any different than they already do since they will never know the server's name. But it is much easier to store and recognise license files if not all have the same name.
