title: How to change the message "The page cannot be displayed because an internal server error has occurred." on IIS error 500"?
body: <p>I'm trying to specify a custom error page to 500 <code>IIS</code> error code, I have following code.</p>
  
  <p><strong>config:</strong></p>
  
  <pre><code>&lt;httpErrors errorMode="Custom" existingResponse="Replace"&gt;
    &lt;clear/&gt;
    &lt;error
      statusCode="500"
      path="/Views/Error/page500.html"
      responseMode="File"/&gt;
  &lt;/httpErrors&gt;
  </code></pre>
  
  <p>My html page500 file is in this route: <code>/Views/Error/page500.html</code>, I'm using sitecore CMS, then I trigger an error 500 turning off the <code>DataBase</code> engine, then my web crashes with a 500 internal server error but instead of show <code>page500.htm</code>l.
  The Error message:</p>
  
  <blockquote>
    <p>"The page cannot be displayed because an internal server error has
    occurred." on <code>IIS</code> error 500" is showed.</p>
  </blockquote>
  
  <p>I dont understand why, I need <code>page500.html</code> showed when 500 code <code>IIS</code> is triggered.</p>
