Referer white list

The Referer white list is an access control list, which is a hotlinking prevention method based on HTTP header referer field, with the purpose of preventing the data stored by the user on BOS from being hotlinked by other people. The user can set the white list of Referer field by BOS console. After the white list is set, only the users in the white list of Referer field can access the data stored in Bucket, and those request outside the white list will be refused. However, if the user's Referer is null, it is accessible by default, and is not restricted by white list.

Region
Region represents an independent region and is an important concept in Baidu AI Cloud.

The service of each region is independently deployed, and will not affect each other. The shared data among services need completing by explicit copy. The reference to region in API must uses its ID.

Representational State Transfer

REST is a software architecture style proposed by Dr. Roy Fielding in his Ph.D. dissertation in 2000. Currently in three mainstream Web service implementation schemes, because the REST model is more concise than the complex SOAP and XML-RPC, more and more web services are designed and implemented in REST style. For example, Amazon.com provides a REST-style web service for book searching; the Web service provided by Yahoo is REST-style. It should be noted that REST is design style and not standard. REST is generally based on the use of existing widely popular protocols and standards such as HTTP, URI, and XML, as well as HTML.
