Configure Azure SAS Authentication for REST

See more REST Examples

Demonstrates Rest.SetAuthAzureSas, which associates an AuthAzureSAS provider so requests are authorized with an Azure Shared Access Signature token.

Background. A SAS token grants time-limited, permission-scoped access to Azure Storage resources without exposing the account key on the wire. Use SAS authorization when a query-token approach is preferred over Shared Key headers.
