title: <meta http-equiv="X-UA-Compatible" content="IE=8" /> ignored in RichFaces webapp
body: <p>I'm using JSF 2.0 and RichFaces 3.3.3 on Glassfish 2.1. I've created a web application with a modal panel that works great in my computer (local server). Because of IE9 incompatibility of the specific RichFaces version, I'm using the <code>X-UA-Compatible: IE=8</code> meta tag in my HTML head:</p>
  <pre><code>&lt;meta http-equiv=&quot;X-UA-Compatible&quot; content=&quot;IE=8&quot; /&gt;
  </code></pre>
  <p>The modal panel look like this when I deploy in my local environment:</p>

  <p>But when I deploy in the production server, I've a problem.</p>
  <p>If I use IE with compatibility view

  , my modal panel look like this:</p>

  <p>If I don't use the compatibility view, I see the modal panel but all my ajax buttons don't work.</p>
  <p>How is this caused and how can I solve it?</p>
