摘要： A method of purging cached open files from a client-side delayed close list on a remote file system. The remote file system stores a unique file identifier for each cached open file which is independent of the cached file's namespace. In response to a delete or rename command of a remote target file, the remote file system obtains a target file identifier from the target file's server. The remote file system then compares the target file identifier with each of the cached file's unique file identifier. If a cached file's unique file identifier matches the target file identifier, the cached file is purged from the delayed close list.

摘要翻译： 从远程文件系统上的客户端延迟关闭列表中清除缓存的打开文件的方法。 远程文件系统为每个缓存的打开文件存储唯一的文件标识符，该文件独立于缓存文件的命名空间。 响应于远程目标文件的删除或重命名命令，远程文件系统从目标文件的服务器获取目标文件标识符。 然后，远程文件系统将目标文件标识符与每个缓存文件的唯一文件标识符进行比较。 如果缓存文件的唯一文件标识符与目标文件标识符匹配，则缓存文件将从延迟关闭列表中清除。

摘要： A system and method that automatically and transparently handle client-side caching of network file data, independent of any remote file handling protocol. A protocol-independent client-side caching mechanism is inserted as a service that handles file-related requests directed to a network, and attempts to satisfy the requests via a client-side caching persistent store. By way of pre-process and post-process calls on a file create request, the caching mechanism creates file-related data structures, and overwrites the information in those structures that a buffering service uses to call back to a network redirector, whereby the client-side caching mechanism inserts itself into the communication flow between the network redirector and the buffering service. Once in the flow of communication, network-directed file read and write requests may be transparently handled by the client-side caching mechanism when appropriate, yet the redirector may be instructed to communicate with the server when needed to satisfy the request.

摘要： Access to WebDAV (Distributed Authoring and Versioning) servers is provided in a manner that is essentially transparent to applications. A WebDAV redirector and related components support file system I/O requests and network requests directed to WebDAV servers identified by URI (Universal Resource Identifier) names, or by a drive may be mapped to a WebDAV share. An application's create or open I/O requests directed to a WebDAV server are detected, and result in a local copy of the file being downloaded and cached for local access. When closed, the local file is uploaded to the WebDAV server. Network-related requests such as for browsing that are directed to a WebDAV server are also handled transparently. WebDAV files may be locally encrypted and decrypted at the file system level, transparent to applications and the WebDAV server, via an encrypting file system that performs local encryption and decryption at the local file system level.

摘要： A system and method for implementing a consistent user name-space on networked computing devices is provided. When a network connection between a local or host computing device and one or more remote computing devices is present, remote items are represented using the same methodology as items located on the host computing device. To the user, remote and local items are indistinguishable. When the network connection is lost or items located on a remote computer are otherwise unavailable, the unavailable items remain represented on the host computing device. Unavailable items are represented in a way that informs the user that the items may not be fully accessed.

摘要： The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e.g., client) and/or the client applications across connectivity interruptions and/or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.

摘要翻译： 本发明提供了一种新颖的客户端缓存（CSC）基础设施，其支持目录级别的转换状态，以促进跨客户端和远程服务器之间的连接状态的无缝操作。 更具体地，执行持续高速缓存以跨连接中断和/或带宽改变来保护用户（例如，客户端）和/或客户端应用。 这部分是通过将客户端数据存储器连同适当的文件访问参数一起缓存所需的文件来实现的。 此外，客户端在断开连接期间保持对缓存文件的访问。 此外，路径的一部分可以离线，而上游的其他部分可以保持联机。 CSC在与物理路径上运行的DFS协作的逻辑路径上运行，以跟踪缓存，访问和更改目录中的文件。 此外，无论文件副本是否存在冲突，客户端上的真相都是有利的。
