<PRE>It's not enabled for PATCH or PUT because it makes little sense for 
them. PATCH and PUT are typically used directly on the URI of the 
resource, even when creating it. While you can return a &quot;better URI&quot; for 
the created resource for them, this should be seen as a special case 
rather than the norm. You can still do it by setting the location header 
manually and Cowboy will react accordingly.
