title: How do you override the default 404 page in ServiceStack?
body: <p>I am using ServiceStack and have my own handlers in for any exceptions thrown which works beautifully. However, I cannot seem to find out how to override the default 404 error page returned from ServiceStack. At present the Body looks like this:</p>
  
  <pre><code>Handler for Request not found:

  <p>With obviously a 404 StatusCode.</p>
  
  <p>Any help or direction as to what I need to override or change would be highly appreciated. If you need any further details from me though, please do feel free to ask and I will reply as soon as I can.</p>
