The Background Intelligent Transfer Service (BITS) IIS Server Extension lets you configure an Internet Information Services (IIS) server to allow BITS clients to perform background, resumable file uploads to IIS virtual directories. Upon completion of a file upload, BITS Server can notify a Web application of the new file via the BITS Upload Protocol extension for HTTP POST. Your Web application can then optionally reply to the client's posting. For information about the BITS Upload Protocol extension for HTTP POST, see.https://go.microsoft.com/fwlink/?LinkId=143105.
