Abstract
Architectures and techniques are described that can leverage directory delegation functions or techniques in order to provide cache coherency. The disclosed techniques can operate for a client side cache that exists in either the user space or domain or the kernel space or domain. A directory delegation request can be transmitted to a file system server that requests a notification relating to updates to a specified file system element (e.g., a file). In response to receiving an associated directory delegation notification, information in the notification can be employed to perform a client side cache update procedure and/or a client side cache preload procedure.
