One of my servers is used to serve multiple domains and some subdomains of those. It is using a standard LAMP stack with cPanel for people to configure and monitor their domains. On that server only, a directory called
.well-known keep appearing in each and every folder used as root of a domain or subdomain, so I have now dozens of
.well-known subdirectories in the tree and they are all empty! Deleting them only removes them for a short while, they only appear at some later time, usually a few hours later according to the file timestamp.
Why do these
.well-known directories keep appearing?
What can I do to prevent them from appearing in the future? I found another question saying that they have some use but I have no use for them and they are empty in any case.
