Module:Archive URL counts

Module documentationviewedithistorypurge

• Module:Archive URL counts implements template {{Archive URL counts}}.
• It includes the sub-module Module:Archive URL counts/data which is executed only once per page [not per template invocation] to ensure fast loading times. This sub-module pulls data from Wikimedia Commons:
  • c:Data:Wikipedia statistics/exturls.tab for statistics regarding external archive URLs across all Wikimedia wikis.
  • exturls.tab is updated automatically by the Numberofurl bot.
• The module was originally developed on Enwiki.

The above documentation is transcluded from Module:Archive URL counts/doc. (edit | history)
Editors can experiment in this module's sandbox (create | mirror) and testcases (create) pages.
