Please describe the scenario in which Page is null:

  The page the request occurred on, or null if the
  request isn't associated with a particular page

[Jon Sonesen, 2017/06/02 05:02:57]

Acknowledged.

[Sebastian Noack, 2017/06/01 17:32:21]

The logic above, handling the case of page being non-null, is redundant.

Acknowledged.
