|
||
<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 <code class="module"><a href="../mod/mod_dav.html">mod_dav</a></code>, add the following to a
|
||
container in your <code>httpd.conf</code> file:</p>
|
||
|
||
<div class="example"><p><code>Dav On</code></p></div>
|
||
|
||
<p>This enables the DAV file system provider, which is implemented by
|
||
the <code class="module"><a href="../mod/mod_dav_fs.html">mod_dav_fs</a></code> module. Therefore that module has to
|
||
be compiled into the server or has to be loaded at runtime using the
|
||
<code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code> directive.</p>
|
||
|
||
<p>In order to make it work you have to specify a web-server writable
|
||
filename for the DAV lock database by adding the following to the
|
||
global section in your <code>httpd.conf</code> file:</p>
|
||
|
||
<div class="example"><p><code>
|
||
DavLockDB /tmp/DavLock
|
||
</code></p></div>
|
||
|
||
<p>You may wish to add a <code class="directive"><a href="../mod/core.html#limit"><Limit></a></code> clause inside the <code class="directive"><a href="../mod/core.html#location"><Location></a></code> directive to limit access to
|
||
DAV-enabled locations. If you want to set the maximum amount of
|
||
bytes that a DAV client can send at one request, you have to use
|
||
the <code class="directive"><a href="../mod/core.html#limitxmlrequestbody">LimitXMLRequestBody</a></code>
|
||
directive. The "normal" <code class="directive"><a href="../mod/core.html#limitrequestbody">LimitRequestBody</a></code> directive has no effect on DAV
|
||
requests.</p>
|
||
|
||
<div class="example"><h3>Full Example</h3><p><code>
|
||
DavLockDB /tmp/DavLock<br />
|
||
<br />
|
||
<Location /foo><br />
|
||
<span class="indent">

|

</code></p></div>
|
||
|
||
<div class="warning"><h3>Security</h3>
|
||
<p>The use of HTTP Basic Authentication is not recommended. You
|
||
should use at least HTTP Digest Authentication, which is provided by
|
||
the <code class="module"><a href="../mod/mod_auth_digest.html">mod_auth_digest</a></code> module. Nearly all WebDAV clients
|
||
support this authentication method. Of course, Basic Authentication
|
||
over an <a href="../ssl/">SSL</a> enabled connection is secure,
|
||
too.</p>

<p>Use the <code class="directive">Dav</code> directive to enable the
|
||
WebDAV HTTP methods for the given container:</p>
|
||
|
||
<div class="example"><p><code>
|
||
<Location /foo><br />
|
||
<span class="indent">
|
||
Dav On<br />
|
||
</span>
|
||
</Location>
|
||
</code></p></div>
|
||
|
||
<p>The value <code>On</code> is actually an alias for the default
|
||
provider <code>filesystem</code> which is served by the <code class="module"><a href="../mod/mod_dav_fs.html">mod_dav_fs</a></code> module. Note, that once you have DAV enabled
|
||
for some location, it <em>cannot</em> be disabled for sublocations.
|
||
For a complete configuration example have a look at the <a href="#example">section above</a>.</p>
|
||
|
||
<div class="warning">
|
||
Do not enable WebDAV until you have secured your server. Otherwise

<p>Use the <code class="directive">DavDepthInfinity</code> directive to
|
||
allow the processing of <code>PROPFIND</code> 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>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>
