' Demonstrates how to use older AWS S3 Signature Version 2 for uploading the contents
' of a string variable to an object in a bucket.

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

set rest = Server.CreateObject("Chilkat.Rest")

' Connect to the Amazon AWS REST server.
bTls = 1
port = 443

' The file is uploaded to the bucket named "chilkat100", which becomes part of the domain:
success = rest.Connect("chilkat100.s3.amazonaws.com",port,bTls,bAutoReconnect)

' ----------------------------------------------------------------------------
' Important: For buckets created in regions outside us-east-1,
' there are three important changes that need to be made.
' See Working with S3 Buckets in Non-us-east-1 Regions for the details.
' ----------------------------------------------------------------------------

' Provide AWS credentials for the REST call.

' For AWS Signature Version 2, the following two properties need to be set:
authAws.SignatureVersion = 2
' See http://docs.aws.amazon.com/AmazonS3/latest/dev/RESTAuthentication.html#ConstructingTheCanonicalizedResourceElement
' The bucket is "chilkat100", and the uriPath is "/hamlet_play.xml", which must match
' the URI path passed to the FullRequestString method below.
authAws.CanonicalizedResourceV2 = "/chilkat100/hamlet_play.xml"

' Load a text file into memory.

' header to "gzip" or "deflate".  (this is optional)

' by the server immediately after receiving the request header, it can respond
' and the client (Chilkat) can avoid sending the file data.
