2.5.4.3.3 BITS--HTTP Metadata Retrieval

Goal: Retrieve metadata from a content server website with content caching support enabled by using the Background Intelligent Transfer Service (BITS).

Context of Use: The user has located a file on a content server (a web server on a wide area network (WAN) link) and wants to read that file. The file is located on a website with caching support enabled. The file is not initially on the LAN and has to be retrieved across a WAN link.

Minimal Guarantees: No action is taken that affects other files that are exposed on the content server as a result of this operation. HTTP access operates with no content caching.

Success Guarantee: The user opens the channel to access the file.

Trigger: An application performs a read operation on content that is located on a WAN link.
