Enabling BranchCache causes a copy of the file that is accessed from a file or Web server and located in a remote office to be cached in the local branch office. The next time a client requests the file, BranchCache first attempts to retrieve it from the local BranchCache.
BranchCache makes sure clients are authorized by the content server and the files are up-to-date, so clients never have to worry about retrieving files that are not current.
- BranchCache clients must be running Windows 7 and the BranchCache feature has to be enabled.
- Web servers must be running Windows Server 2008 R2 with the BranchCache feature enabled.
