Answer 1

You can stream the file from Amazon S3 to the client through your server without downloading the file to your server, by opening a stream to the Amazon S3 file then read from it and write on the client stream (buffer by buffer).

Sample Code:

byte[] buffer = new byte[BUFFER_SIZE];                
GetObjectRequest getObjRequest = new GetObjectRequest().WithBucketName(Bucket_Name).WithKey(Object_Key);

using (GetObjectResponse getObjRespone = amazonS3Client.GetObject(getObjRequest))
using (Stream amazonStream = getObjRespone.ResponseStream)
{
    int bytesReaded = 0;        
    Response.AddHeader("Content-Length", getObjRespone.ContentLength.ToString());

    while ((bytesReaded = amazonStream.Read(buffer, 0, buffer.Length)) > 0 && Response.IsClientConnected)
    {
        Response.OutputStream.Write(buffer, 0, bytesReaded);
        Response.OutputStream.Flush();
        buffer = new byte[BUFFER_SIZE];
    }
}
