How to enable external download server?

i’m sorry to revive this topic but is it safe for ressources when it’s on a external download server ? anyone with the link can download or there is a minimum of security ? if no security with the basic system what should i add or configure it to get it secure ?

Client-side resource files are never secure, they are literally being downloaded by the client. What you could do is only upload the client-side files and keep the server files on the server

No i mean if someone find the link of the server where all ressources are saved, as it is a Nginx server maybe he can download all file; like Server and Client side

that what i mean

Like the same as he would download them while connecting to your server.
