BranchCache is a wide area network (WAN) bandwidth optimization technology that is included in some editions of the Windows Server® 2008 R2 and Windows® 7 operating systems. To optimize WAN bandwidth, BranchCache copies content from your main office 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.  image

This deployment guide provides instructions on deploying BranchCache in both distributed cache mode and hosted cache mode, and allows you to deploy Hypertext Transfer protocol (HHTP), Background Intelligent Transfer Service (BITS), and Server Message Block (SMB)-based content servers that are Web servers, application servers, and file servers, respectively.
