<p>This module provides class 1 and class 2 <a href="http://www.webdav.org">WebDAV</a> ('Web-based Distributed
Authoring and Versioning') functionality for Apache. This
extension to the HTTP protocol allows creating, moving,
copying, and deleting resources and collections on a remote web
server.</p>
<p>To enable mod_dav, add the following to a container in your
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>Dav On</code></td></tr></table></blockquote>
<p>Also, specify a valid filename for the DAV lock database by
adding the following to the global section in your
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>DavLockDB /tmp/DavLock
<em>(Any web-server writable filename, without an
extension)</em>
</code></td></tr></table></blockquote>

<p>Use the <code class="directive">DavDepthInfinity</code> directive to
allow the processing of PROPFIND requests containing the header
'Depth: Infinity'. Because this type of request could constitute a
denial-of-service attack, by default it is not allowed.</p>

<p>Use the <code class="directive">DavLockDB</code> directive to specify
the full path to the lock database, excluding an extension. The
default (file system) implementation of mod_dav uses a SDBM
database to track user locks. The utility
to display all locks in a lock database.</p>

<p>When a client requests a DAV resource lock, it can also
specify a time when the lock will be automatically removed by
the server. This value is only a request, and the server can
ignore it or inform the client of an arbitrary value.</p>
<p>Use the <code class="directive">DavMinTimeout</code> directive to specify, in
seconds, the minimum lock timeout to return to a client.
Microsoft Web Folders defaults to a timeout of 120 seconds; the
<code class="directive">DavMinTimeout</code> can override this to a higher value
(like 600 seconds) to reduce the chance of the client losing
the lock due to network latency.</p>
