title: How can you change the default ContentType in ServiceStack?
body: <p>I have <a href="http://www.servicestack.net/ServiceStack.Northwind/vcard-format.htm" rel="nofollow">registered a new content type</a> in ServiceStack with: </p>
  
  <pre><code>appHost.ContentTypeFilters.Register("application/x-my-content-type", 
     SerializeToStream, DeserializeFromStream);
  </code></pre>
  
  <p>And everything works as expected, if the client sends the content type in the http stream. </p>
  
  <p>Unfortunately, I have a client that is not in my control of HTTP Request Heads and does not send the content type. </p>
  
  <p>How can I get ServiceStack to set the default content type for that route?</p>
