Details

Array of invalid page redirect targets.

Attempting to create a redirect to any of the pages in this array will make the redirect fail. Special:Userlogout is hard-coded, so it does not need to be listed here.

As of now, this only checks special pages. Redirects to pages in other namespaces cannot be invalidated by this variable.
