Manual:Purge

Purging forces the MediaWiki software and a page to rebuild itself; it is in this way not dissimilar to web browser refreshment. It is typically utilised to clear the cache and ensure that changes are immediately visible to everyone.

To manually clear the webpage cache, add  to the URL of the page you are viewing. For example:

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

If you use long style URLs, you'll need this syntax:

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

Remember to change the "example.org" to match the host name of your actual Wiki.

If you purge a page this way without being logged into the wiki, a confirmation form will come up asking you to confirm that you want to purge the page. This is a precaution to keep web spiders from purging pages accidentally when following links.

Note that if you use this method on an image description page, it will additionally purge all cached thumbnails for the image.
