LoadModule mod_proxy_protocol.c
</pre>
<b>Note</b> that using <code>mod_proxy_protocol</code> as a shared module
is <i>required</i> in cases where you want to use both
<code>mod_proxy_protocol</code> <i>and</i> <code>mod_ifsession</code>. For
example, perhaps you want to use <code>mod_ifsession</code> to change the
behavior of some module, <i>e.g.</i> <code>mod_ban</code>, based on the IP
address of the original client. This means that <code>mod_proxy_protocol</code>
would need to hande the connection <i>first</i>, so that it can decode the
<code>PROXY</code> protocol and set the correct client IP address.
<i>However</i>, the ProFTPD build system is hardcoded to ensure that the
<code>mod_ifsession</code> will always be first -- <i>if</i> using static
modules. By using <i>shared</i> modules, you can enforce the proper ordering
using the <code>LoadModule</code> directive, like so:
<pre>
&lt;IfModule mod_dso.c&gt;
...
LoadModule mod_ifsession.c
LoadModule mod_proxy_protocol.c
&lt;/IfModule&gt;
</pre>
The <i>last</i> module loaded will be the <i>first</i> module called.
