<h3>Summary</h3>
+ <div class="warning"><h3><a id="deprecation" name="deprecation">Deprecation</a></h3>
+ <p>Since Apache HTTP Server 2.4.47, protocol Upgrade (tunneling) can be better handled by
+ <code class="module"><a href="../mod/mod_proxy_http.html">mod_proxy_http</a></code>.</p>

<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 tunnelling of web
socket connections to a backend websockets server. The connection
<p>Load balancing for multiple backends can be achieved using <code class="module"><a href="../mod/mod_proxy_balancer.html">mod_proxy_balancer</a></code>.</p>
-<p>In fact the module can be used to upgrade to other protocols, you can set the <code>upgrade</code>
-parameter in the <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code>
-directive to allow the module to accept other protocol.
-NONE means you bypass the check for the header but still upgrade to WebSocket.
-ANY means that <code>Upgrade</code> will read in the request headers and use
-in the response <code>Upgrade</code></p>

+The module can also be used to upgrade to other protocols than WebSocket, by setting
+the <var><a href="mod_proxy.html#upgrade">upgrade</a></var> parameter in the
+<code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code>
+directive to some custom protocol name.
+Special <code>upgrade=NONE</code> and <code>upgrade=ANY</code> values may be used for
+testing/forcing the upgrade but they are <strong>not recommended</strong> for production for
+security reasons.
+<code>NONE</code> means that the check for the header is omitted but still the upgrade to
+WebSocket still happens.
+<code>ANY</code> means that the upgrade will happen with any protocol asked by the client.
