 <p>If you use JSF 1.2 or higher you need change it like this:</p> <pre><code>&lt;h:head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt; &lt;meta http-equiv="cache-control" content="no-cache" /&gt; &lt;meta http-equiv="pragma" content="no-cache" /&gt; &lt;meta http-equiv="expires" content="0" /&gt; &lt;/h:head&gt; </code></pre> <p>it can be part of template.xhtml</p>
