Editing Manual/Purge

<languages />
<translate><!--T:1--> '''Purging''' forces MediaWiki to clear the cached version of a given page, forcing the page to be redisplayed from its source or scripts to restart.</translate>
<translate><!--T:2--> It is used to ensure that recent changes are made immediately visible.</translate>

<translate><!--T:3--> One way to purge a MediaWiki page is to click a page's <tvar name=1></tvar> tab, then in your browser's location field delete just the word <tvar name=2><code>history</code></tvar> off the end of the URL, type <tvar name=3><code>purge</code></tvar> (after the <tvar name=4><code>=</code></tvar>) on the end of the URL, and hit <tvar name=5></tvar>.</translate>
<translate><!--T:4--> Your URL should look something like one of the ones below.</translate>

<translate>
==Examples== <!--T:5-->

<!--T:6-->
* To purge a page, add <tvar name=purge><code>?action=purge</code></tvar> to the URL of the page you are viewing.</translate> <translate><!--T:7--> For example:</translate>

: <code><nowiki>http://example.org/wiki/Main_Page</nowiki>'''?action=purge'''</code>

<translate>
<!--T:8-->
* If the URL has other parameters in its query string, add the purge action to the query string with an ampersand (<tvar name=1>&</tvar>).</translate> <translate><!--T:9--> For example:</translate>

: <code><nowiki>http://example.org/wiki/index.php?title=Main_Page</nowiki>'''&action=purge'''</code>



<translate>
== Requests must be confirmed== <!--T:11-->
</translate>
<translate><!--T:12--> Purge requests made via POST are automatically filled.</translate>
<translate><!--T:13--> Users making purge requests via a query string will be presented with a confirmation form.</translate><ref>[[gerrit:304157]]</ref>
<translate><!--T:14--> This form must be submitted before the purge request will be completed.</translate>
<translate><!--T:15--> This behavior is a precaution to keep web spiders from accidentally purging pages when following links.</translate>

<translate>
==Purge and image thumbnails== <!--T:16-->

<!--T:17-->
If purge is run on an image description page, the cached thumbnails for the image will be purged.

==Categories== <!--T:32-->
</translate>

<translate>
<!--T:33-->
If purge is run on a category with less than 5000 members, the category will be recounted from scratch (<tvar name=1>[[phab:T85696|T85696]]</tvar>).

==Null edits== <!--T:18-->
</translate>

<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>}}

'' which are created automatically to represent loggable actions in the page history.</translate> <translate><!--T:36--> Dummy revisions are sometimes called "null revisions", but that should be avoided to prevent confusion.</translate>}}
