{{lua|Module:Purge}}
{{used in system}}
{{tlx|Purge}} produces a link that will [[WP:PURGE|purge the page's cache]] and rebuild it from the wikitext.

==Purpose==
For efficiency in service, [[MediaWiki]] [[Cache (computing)|cache]]s 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 Depending on the exact sequence of actions editors follow, one may view an out-of-date version of a given page.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 [[Wikipedia:Transclusion costs and benefits|transclusion]]. 

{{tlx|Purge}} adds to any page a link that, when clicked, not only reloads the page, but [[WP:PURGE|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.

|-
| {{tlx|Purge|Purge this page's server cache.}}
| {{Purge|Purge this page's server cache.}}
| Creates a purge link for the page it is used on, but with the text "Purge this page's server cache."
|-
| {{tlx|Purge|page{{=}}Main Page}}
| {{Purge|page=Main Page}}
| Creates a purge link for [[Main Page]].
|-
| {{tlx|Purge|Purge this page's server cache.|page{{=}}Main Page}}
| {{Purge|Purge this page's server cache.|page=Main Page}}
| Creates a purge link for [[Main Page]], but with the text "Purge this page's server cache."
|-
| {{tlx|Purge|anchor{{=}}TemplateData}}
| {{Purge|anchor=TemplateData}}
| Creates a purge link for the page it is used on, which points to the "TemplateData" section.

When you are linking to a section, purging that page will cause you to lose the section link.
