Description:

mod_dav is an Apache module to provide DAV capabilities (RFC 2518)
for your Apache 1.3.x web server.

From http://www.webdav.org:

"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."

DAV functionality includes creating, moving, copying, and deleting
files and directories on a remote web server. Utilizing DAV requires
both a DAV-aware client and server. mod_dav provides complete class 1
and 2 DAV services to DAV clients via the Apache webserver (1.3.4 or
later). The number of DAV-aware clients is growing and includes the
'Web Folders' used in Microsoft Internet Explorer 5.0 and Office 2000.
