DAV-Ext

This module extends WebDAV support with the PROPFIND, OPTIONS, LOCK, and UNLOCK methods.

The standard DAV module provides a partial implementation of WebDAV and supports only the GET, HEAD, PUT, DELETE, MKCOL, COPY, and MOVE methods. For full WebDAV support, you need to enable the standard http_dav_module module, as well as this module for the missing methods.
