title: CORS with com.sun.net.httpserver
body: <p>I am using this code but Chrome will not show me the headers, it seems that there are not added:</p>
  
  <pre><code>Headers headers = httpExchange.getResponseHeaders();
  headers.add("Access-Control-Allow-Headers","x-prototype-version,x-requested-with");
  headers.add("Access-Control-Allow-Methods","GET,POST");
  headers.add("Access-Control-Allow-Origin","*");
  
  httpExchange.sendResponseHeaders(responseCode, responseBody.length());
  OutputStream os = httpExchange.getResponseBody();
  os.write(responseBody.getBytes());
  os.close();
  </code></pre>
  
  <p>What am I doing wrong?</p>
