title: How do I set the correct Content-Type header for the different browsers?
body: <p>I'm running an Apache server to host my websites. They are all written in XHTML5 so I <strong>WANT</strong> to serve them as <code>application/xhtml+xml</code>.</p>
  
  <p>The default on Apache is to serve pages as <code>text/html</code>.</p>
  
  <p>Is there a configuration that I can put at the bottom on my config file that will set the response header <code>Content-Type</code> to <code>application/xhtml+xml</code> for the browsers that support it, otherwise serve as <code>text/html</code> (for &lt; IE9 basically.)</p>
