STiB implements the client portion of the Microsoft BITS Upload Protocol, which is an extension to HTTP 1.1. BITS is a Windows service that manages file transfers to and from Web servers. BITS downloads use HTTP, but uploads use a proprietary extension. BITS is a highly used service, since it is responsible for downloading Windows patches and service packs.
