<h3>Summary</h3>
<p>This module <em>requires</em> the service of <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code>. It provides support for the <code>CONNECT</code>
HTTP method. This method is mainly used to tunnel SSL requests
through proxy servers.</p>
<p>Thus, in order to get the ability of handling <code>CONNECT</code>
requests, <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code> and
<code class="module"><a href="../mod/mod_proxy_connect.html">mod_proxy_connect</a></code> have to be present in the server.</p>
<p>CONNECT is also used when the server needs to send an HTTPS request
through a forward proxy. In this case the server acts as a CONNECT client.
This functionality is part of <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code> and
<code class="module"><a href="../mod/mod_proxy_connect.html">mod_proxy_connect</a></code> is not needed in this case.</p>
<div class="warning"><h3>Warning</h3>
<p>Do not enable proxying until you have <a href="mod_proxy.html#access">secured your server</a>. Open proxy
servers are dangerous both to your network and to the Internet at
large.</p>

<p>The <code class="directive">AllowCONNECT</code> directive specifies a list
of port numbers or ranges to which the proxy <code>CONNECT</code> method
may connect. Today's browsers use this method when a <code>https</code>
connection is requested and proxy tunneling over HTTP is in effect.</p>
<p>By default, only the default https port (<code>443</code>) and the
default snews port (<code>563</code>) are enabled. Use the
<code class="directive">AllowCONNECT</code> directive to override this default and
allow connections to the listed ports only.</p>
