title: WebSocket compression in netty
body: <p>In the <a href="https://github.com/netty/netty/blob/ed4a89082bb29b9e7d869c5d25d6b9ea8fc9d25b/example/src/main/java/io/netty/example/http/websocketx/server/WebSocketServerInitializer.java" rel="nofollow">WebSocket-Server example</a> from the netty repository the WebSocket-Server gets initialized like this</p>
  
  <pre><code>@Override
  public void initChannel(SocketChannel ch) throws Exception {
      ChannelPipeline pipeline = ch.pipeline();
      if (sslCtx != null) {
          pipeline.addLast(sslCtx.newHandler(ch.alloc()));
      }
      pipeline.addLast(new HttpServerCodec());
      pipeline.addLast(new HttpObjectAggregator(65536));
      pipeline.addLast(new WebSocketServerCompressionHandler());
      pipeline.addLast(new WebSocketServerHandler());
  }
  </code></pre>
  
  <p>But the <strong>WebSocketServerCompressionHandler</strong> is not shipped with the <strong>netty-all</strong> package. Is it an outdated example or am I missing another package.</p>
