title: @font-face in IE: Avoid always downloading font?
body: <p>When using an IE specific font-face declaration like below:</p>
  
  <pre><code>@font-face{
      font-family:'Arial Narrow';
      font-style:normal;
      font-weight:normal;
      src:url('../fonts/ArialNarrow.eot');
      src:local('Arial Narrow'),
      local('ArialNarrow'),
      url('../fonts/ArialNarrow.eot') format('embedded-opentype'),
      url('../fonts/ArialNarrow.woff') format('woff');
  }
  </code></pre>
  
  <p>From what I can see, even though the font exists as a system font, it insists on downloading the font that my sheet suggests every time. In order to be more efficient, is there a way to only download the font in IE if it's necessary?</p>
