HotLink Protection is a tool used to prevent other websites from directly linking to files and pictures on your website. It means when other website visits, it cannot load pictures from your pages. This is one of the ways for limiting outbound traffic for the website. In Plesk, the utility hotlink_protection is used for configuring protection from hot-linking on domains. This utility can be used to setup a hotlink protection for a domain and also retrieves the current configuration of domain hotlink protection. The following command can be used to enable/disable hotlinking protection for a domain.
To enable, use the command
hotlink_protection --update domainname.com -enabled true
To disable, use the command
hotlink_protection --update domainname.com -enabled false
