VERIFICATION METHOD FOR CDN RETURN-TO-SOURCE, VERIFICATION SERVER, AND CDN CLUSTER

摘要

Disclosed in the embodiments of the present application are a verification method for CDN return-to-source, a verification server, a computer readable storage medium, and a CDN cluster. The verification method provided by one embodiment of the present application is implemented by the verification server in the CDN cluster, and comprises the steps: obtaining a return-to-source URL of a cache server in the CDN cluster; obtaining, from the cache server in the CDN cluster according to the return-to-source URL, a complete resource corresponding to the return-to-source URL; on the basis of the obtained complete resource, calculating a first verification value according to a first algorithm; obtaining a second verification value that is generated, according to the first algorithm, by a source station on the basis of the complete resource stored by the source station and corresponding to the return-to-source URL; and in the case that the first verification value and the second verification value corresponding to the return-to-source URL are identical, indicating that verification is successful.
