<h3>Sommaire</h3>
<p>Pour utiliser ce module, <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code> doit être
chargé. Il fournit le support du tunnelling pour les connexions
websocket vers un serveur websockets d'arrière-plan. La connexion
est automatiquement promue en connexion websocket :</p>
<div class="example"><h3>Réponse HTTP</h3><pre class="prettyprint lang-config">Upgrade: WebSocket
Connection: Upgrade</pre>
</div>
<p>Le mandatement des requêtes vers un serveur websockets comme
<code>echo.websocket.org</code> peut être configuré via la directive <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> :</p>
<pre class="prettyprint lang-config">ProxyPass "/ws2/" "ws://echo.websocket.org/"
ProxyPass "/wss2/" "wss://echo.websocket.org/"</pre>
<p>Il est possible de mandater les websockets et HTTP en même temps, avec un jeu
spécifique d'URLs pour les websockets, en définissant la directive <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code> concernant les
websockets avant celle concernant HTTP :</p>
<pre class="prettyprint lang-config">ProxyPassMatch ^/(myApp/ws)$ ws://backend.example.com:9080/$1
ProxyPass / http://backend.example.com:9080/</pre>
<p>Il est possible de mandater les websockets et HTTP en même temps, lorsque
les URLs websockets ne concernent pas uniquement les websockets ou ne sont pas
connues à l'avance, en utilisant la directive <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> pour configurer le mandatement des
websockets :</p>
<pre class="prettyprint lang-config">ProxyPass / http://example.com:9080/
RewriteEngine on
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteCond %{HTTP:Connection} upgrade [NC]
RewriteRule ^/?(.*) "ws://example.com:9080/$1" [P,L]</pre>
<p>La répartition de charge entre plusieurs serveurs d'arrière-plan peut être
configurée via le module <code class="module"><a href="../mod/mod_proxy_balancer.html">mod_proxy_balancer</a></code>.</p>
<p>En fait, ce module permet d'accepter d'autres protocoles ; vous pouvez à cet
effet utiliser le paramètre <code>upgrade</code> de la directive <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code>. La valeur NONE
signifie que vous court-circuitez la consultation de l'en-tête, mais que vous
autorisez quand-même WebSocket. La valeur ANY signifie que <code>Upgrade</code>
va lire les en-têtes de la requête et les utilisera dans l'en-tête
<code>Upgrade</code> de la réponse.</p>
