ASP.NET Metatag element
<p>Im trying to add metatag programatically to my page in asp.net using:</p>

<pre><code>HtmlMeta meta = new HtmlMeta();
meta.Name = "keywords";
meta.Content = "test,test1";
this.Master.Page.Header.Controls.Add(meta);
</code></pre>

<p>but the Master.Page.Header is always NULL.</p>

<p>Any ideias?</p>
