WebDAV is a protocol for author collaboration and managing documents that are stored on a web server.
WebDAV stands for "Web-based Distributed Authoring and Versioning". It is a set of extensions to the HTTP protocol which allows users to collaboratively edit and manage files on remote web servers. Essentially WebDAV makes the web both readable and writable. It also manages the documents and can provide a version control system. Clients can be using Linux, Windows (Webfolders), or MacOS X. At the heart of WebDAV is the idea of a secure Internet environment. Mobile devices using iOS or Android also can be clients.
