Generate presigned url with ACL

[knopa]

Is there any chance to do that without additional roundtrip after uploading?
For example set x-amz-acl as allowed in parameters?

This is possible, though you'll need to specify the same header both when creating the presigned url and when using it. Here's an example.

using(var client = new AmazonS3Client(creds, RegionEndpoint.USWest2))
{
    var presignedRequest = new GetPreSignedUrlRequest
    {
        BucketName = bucketName,
        Key = key,
        Verb = HttpVerb.PUT,
        Expires = DateTime.Now.AddDays(1)
    };
    presignedRequest.Headers["x-amz-acl"] = "public-read";
    var url = client.GetPreSignedURL(presignedRequest);

    var request = HttpWebRequest.Create(url) as HttpWebRequest;
    request.Headers["x-amz-acl"] = "public-read";
    request.Method = "PUT";
    using(var writer = new StreamWriter(request.GetRequestStream()))
    {
        writer.WriteLine("Test content");
    }

    using(var resposne = request.GetResponse())
    {

    }
}

But, when put are doing not on your side?

The x-amz-acl header would have to be specified by the uploader.
