AutoVersioning is disabled by default in DeltaV sample.
See Implementing Resumable Upload and AJAX Upload & Progress Bar.
Streamlined Upload in IIS
When a file is being uploaded to server running as ASP.NET application in IIS the file will be first saved to temporary upload folder. Only when entire file is uploaded it will become available for .NET user code. This limitation makes creating an upload progress service a difficult task. WebDAV Server Engine provides ResumableUploadModule that significantly improves performance and solves upload buffering problem in IIS/ASP.NET opening way to creating servers with rich upload functionality.
