Template:Purge/doc
 | This is a documentation subpage for Template:Purge. It may contain usage information, categories and other content that is not part of the original template page. |
 | This template is used in system messages, and on approximately 440,000 pages, or roughly 1% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them. |

{{Purge}} produces a link that will purge the page's cache and rebuild it from the wikitext.
Purpose
[edit]For efficiency in service, MediaWiki caches pages. Depending on the exact sequence of actions editors follow, one may view an out-of-date version of a given page. This happens most often on heavily-edited pages and on pages which contain an instance of transclusion.
{{Purge}} adds to any page a link that, when clicked, not only reloads the page, but clears the server cache, forcing the page to be completely rendered "from scratch". This is not a one-time solution; generally, editing a page is itself sufficient to purge cache. Rather, it is a measure taken in anticipation of the frequent need to purge.
Examples
