Hotlink protection

OSS is a Pay-As-You-Go service. To prevent users’ data on the OSS from being leeched, OSS supports hotlink protection based on the referer field in the HTTP header.

To prevent your data on OSS from being leeched, OSS supports hotlink protection through the referer field settings in the HTTP header, including the following parameters:

• Referer whitelist: Used to allow access only for specified domains to OSS data.
• Empty referer: Determines whether the referer can be empty. If it is not allowed, only requests with the referer filed in their HTTP or HTTPS headers can access OSS data.

For more information about the OSS hotlink protection features, see Configure hotlinking protection.
