title: Force IE 11 "User agent string" using tags
body: <p>My website is broken in IE11. </p>
  
  <p>We all know that HTML tags allow developer to force IE compatibility mode; in example</p>
  
  <pre><code>&lt;meta http-equiv="X-UA-Compatible" content="IE=8, IE=9" /&gt;
  </code></pre>
  
  <p>worked great and solved the visualization problems for IE10.</p>
  
  <p>But actually on IE11, even if <code>Compatibility mode</code> is set to <code>IE9</code>, <code>User agent string</code> is set to <code>default</code> and javascript doesn't work.
  Changing manually <code>User agent string</code> to <code>IE10</code> solved my problems.</p>
  
  <p>For shure I'm going to solve the real problems that cause website errors, but actually <strong>I need a fast, programatic way to force  "User agent string" to IE10</strong>, since I can't contact every user.</p>
  
  <p>Can someone help?</p>
