<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>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"><Proxy www.example.com:443>

Require ip 192.168.0.0/16

|
||
<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>
