Example 3 with WebSocketServerHandshaker

use of io.netty.handler.codec.http.websocketx.WebSocketServerHandshaker in project vert.x by eclipse.

the class HttpServerImpl method createHandshaker.

    // As a fun part, Firefox 6.0.2 supports Websockets protocol '7'. But,
    // it doesn't send a normal 'Connection: Upgrade' header. Instead it
    // sends: 'Connection: keep-alive, Upgrade'. Brilliant.
    String connectionHeader = request.headers().get(io.vertx.core.http.HttpHeaders.CONNECTION);
    if (connectionHeader == null || !connectionHeader.toLowerCase().contains("upgrade")) {
        sendError("\"Connection\" must be \"Upgrade\".", BAD_REQUEST, ch);
