<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><code class="module"><a href="../mod/mod_proxy_connect.html">mod_proxy_connect</a></code> creates the following request notes for
        logging using the <code>%{VARNAME}n</code> format in
        <code class="directive"><a href="../mod/mod_log_config.html#logformat">LogFormat</a></code> or
        <code class="directive"><a href="../mod/core.html#errorlogformat">ErrorLogFormat</a></code>:

    <dl>
        <dt>proxy-source-port</dt>
        <dd>The local port used for the connection to the backend server.</dd>
    </dl>

   <p>CONNECT method requests are controlled by the
   <code class="directive"><a href="../mod/mod_proxy.html#proxy">Proxy</a></code> block
   as any other HTTP request going through.
   SSL connections through a proxy may be filtered explicitly
   by specifying the target host and port, for instance:
   </p>

   <pre class="prettyprint lang-config">&lt;Proxy www.example.com:443&gt;
  Require ip 192.168.0.0/16
&lt;/Proxy&gt;</pre>

</table>
    <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>

    <p>Set the value to <code>None</code> to disallow <code>CONNECT</code>
    requests to all ports, including the defaults.  <code>None</code> cannot
    be combined with port numbers in the same context.</p>

    <p>Where <code class="directive">AllowCONNECT</code> is set in both the main
    server and a virtual host, the lists of ports are merged, so a virtual
    host may permit additional ports.  A value of <code>None</code> takes
    precedence and disallows all ports where it is set; but an inherited
    <code>None</code> is in turn overridden by an explicit list of ports in a
    virtual host.</p>
