Example 6 with HttpVersion

use of io.netty.handler.codec.http.HttpVersion in project zuul by Netflix.

the class ClientResponseWriter method buildHttpResponse.

    final DefaultHttpResponse nativeResponse = new DefaultHttpResponse(responseHttpVersion, HttpResponseStatus.valueOf(zuulResp.getStatus()), false, false);
