body: <p>PF 3.5(4.0), Omnifaces 1.6.3, Mojara 2.1.21</p>
  
  <p>Is it possible to control  http headers which will be sent  inside of JSF xhtml page ? I mean something like: </p>
  
  <p><strong>.xhtml</strong>:</p>
  
  <pre><code>&lt;html xmlns:http="a cool name space"&gt;
  
    &lt;h:head&gt;
      &lt;http:headers header="Cache-Control" value="no-cache, no-store, must-revalidate" /&gt;
    &lt;/h:head&gt;
    &lt;h:body&gt; .... &lt;/h:body&gt;
  &lt;/html&gt;
  </code></pre>
