Applies To: Windows 8

BranchCache is a wide area network (WAN) bandwidth optimization technology that is included in some editions of the Windows Server® 2012 and Windows® 8 operating systems, as well as in some editions of Windows Server 2008 R2 and Windows 7. To optimize WAN bandwidth when users access content on remote servers, BranchCache copies content from your main office or hosted cloud content servers and caches the content at branch office locations, allowing client computers at branch offices to access the content locally rather than over the WAN.


If you use BranchCache for SMB caching of files and folders, do not disable Offline Files. If you disable Offline Files, BranchCache SMB caching does not function correctly.
