<translate><!--T:19--> Purging will only update the rendering of the page, it won't update the link tables.</translate>
<translate><!--T:20--> These tables control lists that the page is listed in (for example, pages listed on category pages, <tvar name=1>[[Special:Whatlinkshere]]</tvar>, along with several other <tvar name=2><code>query</code></tvar> special pages).</translate>
<translate><!--T:21--> In order to force an update of the link tables, you can do what is called a '''null edit''' (or '''purge edit''').</translate>
<translate><!--T:22--> Click on <tvar name=1><code></code></tvar> and save without changing anything.</translate>
<translate><!--T:23--> No entry in the page's history will appear, but all link tables and other derived data should be refreshed.</translate>

<translate><!--T:24--> An alternative way to update the links table is to use the API's <tvar name=purge></tvar> module with the <tvar name=force><code>forcelinkupdate</code></tvar> option.</translate>
<translate><!--T:34--> This however may not update other derived data, such as the search index or resource loader module cache.</translate>

{{Note|1=<translate><!--T:25--> This option only applies to the API.</translate> <translate><!--T:26--> Adding <tvar name=1><code>forcelinkupdate</code></tvar> to an <tvar name=2><code>index.php</code></tvar> URL has no effect.</translate>}}
