Web Distributed Authoring and Versioning (WebDAV) is an application protocol related to HTTP 1.1 that allows clients to transparently publish and manage resources on the World Wide Web. WebDAV is an HTTP extension that adds new methods to HTTP (COPY, MOVE, PROPFIND, PROPMATCH, etc.) It allows users to edit and manage files collaboratively on remote Web servers.

Filters in the HTTP Inspection feature identify WebDAV traffic according to HTTP method.
