' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Rest")
set rest = Server.CreateObject("Chilkat.Rest")

' Connect to the Azure Storage Blob Service
bTls = 1
port = 443
bAutoReconnect = 1
' In this example, the storage account name is "chilkat".
success = rest.Connect("chilkat.blob.core.windows.net",port,bTls,bAutoReconnect)
If (success <> 1) Then
    Response.Write "<pre>" & Server.HTMLEncode( rest.LastErrorText) & "</pre>"
    Response.End

' Provide Azure Cloud credentials for the REST call.
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.AuthAzureStorage")
set azAuth = Server.CreateObject("Chilkat.AuthAzureStorage")

' The account name used here should match the 1st part of the domain passed in the call to Connect (above).
azAuth.Account = "chilkat"

' This causes the "x-ms-version: 2021-08-06" header to be automatically added.

' Note: The application does not need to explicitly set the following
' headers: x-ms-date, Authorization.  These headers
' are automatically set by Chilkat.

' To call Delete Container on a container that has an active lease, specify the lease ID in this header. 
' If this header is not specified when there is an active lease, Delete Container will return 409 (Conflict). 
' If you specify the wrong lease ID, or a lease ID on a container that does not have an active lease, 
' Delete Container will return 412 (Precondition failed).

' IMPORTANT: Delete this line, or insert a valid lease ID, otherwise the request
' will fail with a 400 status code..
success = rest.AddHeader("x-ms-lease-id","SOME_LEASE_ID")
