' This example assumes the Chilkat HTTP 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.Http")
set http = Server.CreateObject("Chilkat.Http")

' Insert your AccessKey ID here:
http.AwsAccessKey = "access-key"

' Insert your AccessKey Secret here:
http.AwsSecretKey = "secret-key"

' To list objects in a bucket located in a different region, use the endpoint for that region, such as "oss-cn-hangzhou.aliyuncs.com 	"
' See Alibaba Object Storage Service Regions and Endpoints
http.AwsEndpoint = "oss-us-east-1.aliyuncs.com"

    Response.End
End If

Response.Write "<pre>" & Server.HTMLEncode( "Response status code = " & http.LastStatus) & "</pre>"
