Is it possible to send a PATCH request with a complex object in the request body? The following works fine but it sends the object as url parameters not in the request body..

```
  //region - - - - - - - - - - - - - - - update with PATCH
        patch: function(url, obj, funcSuccess){

            // server call
            var resP =  resource(appConfigSvc.apiBaseUrl + url, obj, {
                'update': {
                    method:'PATCH',
                    headers: {'Content-Type': 'application/json' }
                }
            });
            var defer = q.defer();
            resP.update(
                function(data) {
                    defer.resolve(data);
                    if(funcSuccess){
                        funcSuccess(data);
                    }
                },
                function(response) {
                    //responseHandlerSvc.handleResponse(response);
                    defer.reject(response);
                });
            return defer.promise;
        },
        //endregion

```

WebApi doesn't have a problem accepting patch request body. Postman also allows sending patch requests with body. The only problem is Angular $resource.
