in my silex application, here is a sample controller code:

```
$api->match('/product/{id}', function(Request $request, $id) use ($api) {
   //my code here
})->method('DELETE');

```

Here I want to pass this url "/product/5?/testpara=myvalue" and retrieve the 'testpara' parameter's value using the '$request' object. Is it possible? If yes, How?

Problem is, I don't get that value even using $\_REQUEST["testpara"].

Any help is appreciated. Thanks.
