+/// The `Location` header.
+///
+/// The Location response-header field is used to redirect the recipient to 
+/// a location other than the Request-URI for completion of the request or identification 
+/// of a new resource. For 201 (Created) responses, the Location is that of the new 
+/// resource which was created by the request. For 3xx responses, the location SHOULD 
+/// indicate the server's preferred URI for automatic redirection to the resource. 
+/// The field value consists of a single absolute URI.
+///
+/// Currently is just a String, but it should probably become a better type,
+/// like url::Url or something.
