title: Upload File to Amazon S3 from Url [file does not exist error]
body: <p>Currently I am using viddler for different service and videos uploading. I also would like to make a service for content backup on an amazon s3 server. For developing this service I used the AWS SDK for .NET. When I try to upload a file passing the URL as the file path it gives me the following error:<br>
  <code>"the specified file does not exist"</code> </p>
  
  <p>My question is: Does the AWS SDK support content uploading from another domain to s3 programmatically or any other method?</p>
  
  <p>My code:</p>
  
  <pre><code>PutObjectRequest titledRequest = new PutObjectRequest();
  titledRequest.WithMetaData("title", "the title")
  //.WithContentBody("this object has a title")
  .WithBucketName(bucketName)
  .WithFilePath("http://download.microsoft.com/download/9/2/2/9222D67F-7630-4F49-BD26-        476B51517FC1/FileFormatConverters.exe") //does url support? 
  .WithTimeout(3600000)
  .WithReadWriteTimeout(3600000)
  .WithKey("test.ext");
  
  using (S3Response responseWithMetadata = client.PutObject(titledRequest))
  {
  }
  </code></pre>
