Background Intelligent Transfer Service IBackgroundCopyFile5 API sample

This sample demonstrates how to use the new IBackgroundCopyFile5 interface's GetProperty method to obtain the last set of HTTP headers received for each file in a Background Intelligent Transfer Service (BITS) download job. The information in the HTTP header could be used, for example, to determine the file type or when it last changed on the server. Prior to Windows 8.1 and Windows Server 2012 R2, BITS did not provide a means by which the application could retrieve and inspect the HTTP response headers of a completed download. This sample illustrates how to use the BITS API to create a BITS job with multiple URLs to download, list the URLs in a job, and retrieve the HTTP response headers for each URL.

Note The Windows-classic-samples repo contains a variety of code samples that exercise the various programming models, platforms, features, and components available in Windows and/or Windows Server. This repo provides a Visual Studio solution (SLN) file for each sample, along with the source files, assets, resources, and metadata needed to compile and run the sample. For more info about the programming models, platforms, languages, and APIs demonstrated in these samples, check out the documentation on the Windows Dev Center. This sample is provided as-is in order to indicate or demonstrate the functionality of the programming models and feature APIs for Windows and/or Windows Server. This sample was created for Windows 8.1 and/or Windows Server 2012 R2 using Visual Studio 2013, but in many cases it will run unaltered using later versions.
