   1 - Q: How to redirect to another extractor?
   2   - A:
   3     - Most simple using only `url_result`
   4       ```
   5       # get proper url first if needed.
   6       return self.url_result(url)
   7       ```
   8     - Using `_request_webpage` and `to_screen` in addition
   9       ```
  10       urlh = self._request_webpage(
  11           url, id, note='Downloading redirect page')
  12       url = urlh.geturl()
  13       self.to_screen('Following redirect: %s' % url)
  14       return self.url_result(url)
  15       ```
  16     - Using `return` construction
  17       ```
  18       return {
  19             '_type': 'url_transparent',
  20             'url': url,
  21             'ie_key': ExampleIE.ie_key(),
  22             'id': id,
  23         }
  24       # Alternative if extractor supports internal uri like kaltura
  25       return {
  26             '_type': 'url_transparent',
  27             'url': 'kaltura:%s:%s' % (partner_id, kaltura_id),
  28             'ie_key': KalturaIE.ie_key(),
  29             'id': id,
  30         }
  31       ```
