title: 500 Server Error when trying to add a new mimetype
body: <p>I'm trying to add the mimeType application/xml to web.config, but everytime I add it I get a 500 server error. I have no experience with this and any help would be very appreciated. </p>
  
  <pre><code>&lt;configuration&gt;
  &lt;system.web&gt;
      &lt;customErrors mode="Off"/&gt;
      &lt;compilation debug="true"/&gt;
  &lt;/system.web&gt;
  
  &lt;system.webServer&gt;
      &lt;asp scriptErrorSentToBrowser="true"/&gt;
      &lt;httpErrors errorMode="Detailed"/&gt; 
      &lt;mimeMap fileExtension=".xml" mimeType="application/xml " /&gt;
  &lt;/system.webServer&gt;
  </code></pre>
