  13     <p>This module provides class 1 and class 2 <a href="http://www.webdav.org">WebDAV</a> ('Web-based Distributed
  14     Authoring and Versioning') functionality for Apache. This
  15     extension to the HTTP protocol allows creating, moving,
  16     copying, and deleting resources and collections on a remote web
  17     server.</p>

  21
  22 <div class="example"><p><code>Dav On</code></p></div>

  99     <p>When a client requests a DAV resource lock, it can also

 102     ignore it or inform the client of an arbitrary value.</p>

 104     <p>Use the <code class="directive">DavMinTimeout</code> directive to specify, in
 105     seconds, the minimum lock timeout to return to a client.
 106     Microsoft Web Folders defaults to a timeout of 120 seconds; the
 107     <code class="directive">DavMinTimeout</code> can override this to a higher value
 108     (like 600 seconds) to reduce the chance of the client losing
 109     the lock due to network latency.</p>
