Module:Purge

Module documentation[view] [edit] [history] [purge]

This module produces a link to purge a page's cache. This is usually the current page, but can be another page.

Usage

From wiktext

From wikitext, this module should be accessed via Template:Purge. Please see the template page for documentation.

From Lua

From Lua, first you need to load the module:

local mPurge = require('Module:Purge')

Then you can create purge links with the _main function:

mPurge._main(args)

args is a table of arguments, identical to the ones accepted by Template:Purge. Please see the template documentation for more details.
