| <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> |

| </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> |
