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.
Awake File is a framework that allows Android and Java Desktop developers to very easily implement file uploads and downloads through HTTP. Security has been taken into account from the design stage: server side configuration allows you to specify strong security rules in order to protect the files. It allows listing, creation, and deletion of remote directories, calling of remote Java methods, and displays nice progress indicators to your users.
