What is hotlink protection?
Hotlink typically means a situation where other websites link to the files and images on your website, thereby effectively stealing the bandwidth from your site every time a user from the other website clicks the link on the URL taken from your website. This not only clogs your server due to the congestion of bandwidth but also results in your information being stolen and published without due credit or permissions.
Most CMS and hosting service providers give the option of buying protection from hotlinking. This protection comes in the form of a plugin or an addon and this script will be compatible with your web server. An administrator role access file should be created in the root folder which then blocks external web servers from stealing your website’s images or files.
This protection plugin works only with the primary domain. It will not function with the subdomains.
