<hr><br>
<p>
The <code>mod_memcache</code> module enables ProFTPD support for caching
data in <a href="http://memcached.org">memcached</a> servers, using the
<a href="http://libmemcached.org">libmemcached</a> client library. Note
that <code>libmemcached</code> version 0.41 or later is <b>required</b>.

<h2><a name="MemcacheEngine">MemcacheEngine</a></h2>
<strong>Syntax:</strong> MemcacheEngine <em>on|off</em><br>
<strong>Default:</strong> MemcacheEngine off<br>
<strong>Context:</strong> "server config", <code><VirtualHost></code>, <code><Global></code><br>
<strong>Module:</strong> mod_memcache<br>
<strong>Compatibility:</strong> 1.3.4rc2 and later
<p>
The <code>MemcacheEngine</code> directive enables or disables the
<code>mod_memcache</code> module, and thus the configuration of memcache
support for the <code>proftpd</code> daemon.
<p>
<hr>
<h2><a name="MemcacheLog">MemcacheLog</a></h2>
<strong>Syntax:</strong> MemcacheLog <em>path|"none"</em><br>
<strong>Default:</strong> None<br>
<strong>Context:</strong> "server config", <code><VirtualHost></code>, <code><Global></code><br>
<strong>Module:</strong> mod_memcache<br>
<strong>Compatibility:</strong> 1.3.4rc2 and later
<p>
The <code>MemcacheLog</code> directive is used to specify a log file for
<code>mod_memcache</code>'s reporting on a per-server basis. The
<em>file</em> parameter given must be the full path to the file to use for
logging.
<p>
Note that this path must <b>not</b> be to a world-writable directory and,
unless <code>AllowLogSymlinks</code> is explicitly set to <em>on</em>
(generally a bad idea), the path must <b>not</b> be a symbolic link.
<p>
<hr>
<h2><a name="MemcacheOptions">MemcacheOptions</a></h2>
<strong>Syntax:</strong> MemcacheOptions <em>opt1 ... optN</em><br>
<strong>Default:</strong> None<br>
<strong>Context:</strong> "server config", <code><VirtualHost></code>, <code><Global></code><br>
<strong>Module:</strong> mod_memcache<br>
<strong>Compatibility:</strong> 1.3.4rc2 and later
<p>
The currently supported <code>MemcacheOptions</code> are:
<ul>
<li><code>NoBinaryProtocol</code>
</ul>
<p>
<hr>
<h2><a name="MemcacheReplicas">MemcacheReplicas</a></h2>
<strong>Syntax:</strong> MemcacheReplicas <em>count</em><br>
<strong>Default:</strong> None<br>
<strong>Context:</strong> "server config", <code><VirtualHost></code>, <code><Global></code><br>
<strong>Module:</strong> mod_memcache<br>
<strong>Compatibility:</strong> 1.3.4rc2 and later
<p>
<em>Experimental feature</em>
<p>
<hr>
<h2><a name="MemcacheServers">MemcacheServers</a></h2>
<strong>Syntax:</strong> MemcacheServers <em>servers</em><br>
<strong>Default:</strong> None<br>
<strong>Context:</strong> "server config", <code><VirtualHost></code>, <code><Global></code><br>
<strong>Module:</strong> mod_memcache<br>
<strong>Compatibility:</strong> 1.3.4rc2 and later
<p>
The <code>MemcacheServers</code> directive is used to configure the
IP addresses/ports of the <code>memcached</code> servers that the
<code>mod_memcache</code> module is to use. The list of servers is expressed
as a space-delimited list. For example:
<pre>
MemcacheServers 1.2.3.4:11211 1.2.3.5:22422
</pre>
<p>
Alternatively, you can configure a Unix domain socket path using <i>e.g.</i>:
<pre>
MemcacheServers /var/run/memcached.sock
</pre>
<p>
<hr>
<h2><a name="MemcacheTimeouts">MemcacheTimeouts</a></h2>
<strong>Syntax:</strong> MemcacheTimeouts <em>connect read write</em><br>
<strong>Default:</strong> None<br>
<strong>Context:</strong> "server config", <code><VirtualHost></code>, <code><Global></code><br>
<strong>Module:</strong> mod_memcache<br>
<strong>Compatibility:</strong> 1.3.4rc2 and later
<p>
<em>Experimental feature</em>
<p>

<h2><a name="Installation">Installation</a></h2>
The <code>mod_memcache</code> module is distributed with ProFTPD. To enable
support and use of the memcache protocol in your <code>proftpd</code> daemon,
use the <code>--enable-memcache</code> configure option:
<pre>
# ./configure --enable-memcache ...
# make
# make install
</pre>
This option causes the <code>mod_memcache</code> module to be compiled into
<code>proftpd</code>.
<p>
You may also need to tell <code>configure</code> how to find the
<code>libmemcached</code> header and library files:
<pre>
# ./configure --enable-memcache \
--with-includes=<i>/path/to/libmemcached/include</i> \
--with-libraries=<i>/path/to/libmemcached/lib</i>
</pre>
