| <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 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">ProxyPass "/" "ws://backend.example.com:9080/" |
| ProxyPass "/" "http://backend.example.com:9080/"</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> |
