title: Using real HTTP error code in wicket
body: <p>I need to respond with an error code. When I am using <code>AbortWithHttpStatusException</code> my response is like that:</p>
  
  <pre><code>HTTP/1.1 200 OK
  Server: Apache-Coyote/1.1
  portlet.http-status-code: 507
  Content-Type: text/html;charset=UTF-8
  Content-Length: 0
  Date: Tue, 10 Jan 2012 09:49:52 GMT
  </code></pre>
  
  <p>which is interpreted by browser (firefox at least) as 200 OK, which seems ok, since there is <code>HTTP/1.1 200 OK</code> at the beginning. How can I force wicket to return other http code?</p>
  
  <p>I am using wicket 1.4.18</p>
