title: How to write multi cookies from server side to browser?
body: <p>I'm using <a href="http://vertx.io/" rel="nofollow">vert.x</a> to write an application. It doesn't have built-in cookie support yet, and we have to use "putHeader()" method to manually set cookies.</p>
  
  <p>Now I want to set several cookies, so I write:</p>
  
  <pre><code> req.response.putHeader("Set-Cookie", "aaa=111; path=/")
   req.response.putHeader("Set-Cookie", "bbb=222; path=/")
   req.response.putHeader("Set-Cookie", "ccc=333; path=/")
  </code></pre>
  
  <p>But I found vert.x send only one "Set-Cookie":</p>
  
  <pre><code> Set-Cookie ccc=333; path=/
  </code></pre>
  
  <p>I'm not sure if I misunderstand something. Can server send multi "Set-Cookie" commands one time? Is it correct to send multi cookies this way?</p>
