WebDav stands for "Web-based Distributed Authoring and Versioning". It is a set of extensions to the HTTP protocol (IETF RFC 2538) which allows users to collaborativly edit and manage files on remote Web servers, i.e., some of the BSCW features which are available via Web interface (e.g., document upload to a BSCW server or renaming of a document on a BSCW server) are also supported by the WebDAV protocol (see www.webdav.org for software supporting WebDAV standard). In particular, Microsoft Internet Explorer, Windows Explorer and Microsoft Office are supporting the WebDAV protocol.
