Manual:Purge

Overview
Purging forces MediaWiki to clear the cached version of a given page, forcing the page to be redisplayed from its source. It is used to ensure that recent changes are made immediately visible.

Examples

 * To purge a page, add  to the URL of the page you are viewing.  For example:


 *  http://example.org/wiki/Main_Page ?action=purge


 * If the URL has other parameters in its query string, add the purge action to the query string with an ampersand (&). For example:


 *  http://example.org/wiki/index.php?title=Main_Page &action=purge

Remember to change  in the above URLs to the host name of your WikiMedia installation.

Anonymous requests must be confirmed
Purge requests made via POST or by logged-in users are automatically filled. Anonymous users making purge requests via a query string will be presented with a confirmation form. This form must be submitted before the purge request will be completed. This behavior is a precaution to keep web spiders from accidentally purging pages when following links.

Purge and image thumbnails
If purge is run on an image description page, the cached thumbnails for the image will be purged.
