In this case the server acts as a CONNECT client. 48 This functionality is part of <code class="module"><a href="/mod/mod_proxy.html">mod_proxy</a></code> and 49 <code class="module"><a href="/mod/mod_proxy_connect.html">mod_proxy_connect</a></code> is not needed in this case.</p> 50 51 <div class="warning"><h3>Warning</h3> 52 <p>Do not enable proxying until you have <a href="mod_proxy.html#access">secured your server</a>.
