The Interwiki extension adds the "Special:Interwiki" page to MediaWiki, to view and edit the interwiki table, and a log of any actions made with it. This extension works with the $wgInterwikiCache variable. Changes made with it to the interwiki table can affect the behavior of both transclusion and interwiki links. The list of "Special:Interwiki" is identical to the API api.php?action=query&meta=s
