(SQL Server) S3 - Working with Buckets in a Region

Demonstrates how to work with S3 buckets located in a particular region.

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

CREATE PROCEDURE ChilkatSample

    DECLARE @hr int
    DECLARE @sTmp0 nvarchar(4000)
    --  This example requires the Chilkat API to have been previously unlocked.
    --  See Global Unlock Sample for sample code.

    --  When usig the REST class to access an S3 bucket that has been created in a particular region,
    --  there are three important things to remember:
    -- 
    --  1) Connect to the domain that includes the region.  For example, instead of connecting to
    --     "s3.amazonaws.com", connect to "s3.eu-central-1.amazonaws.com" if your bucket is in the EU Frankfurt region.
    --     See http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region   for a list of S3 region domains (endpoints)
    -- 
    --  2) Set the AuthAws.Region property equal to the region, such as "eu-central-1".
    -- 
    --  3) Include the region in request's Host header.
    -- 

    --  This example will upload to a bucket in the eu-central-1 region.
