How to get File URL when storage is Rackspace file system ?

Hi,

I have been using rackspace to upload my files. I managed to upload an image inside my container. But I'm not able to get the file URL.

This is working fine with Image intervention library. This returns the image which is uploaded.

$file = Storage::get('dp.jpg');    
return \Image::make($file)->response(); 

But this is not working.

$file = Storage::url('dp.jpg');   
return dd($file);

Error I get,

This driver does not support retrieving URLs.

Thank You :)
