Help:Purge

The Purge is a way to force an update to the server's cache a wiki page. Some of the biggest reasons it is needed:

• You would like to see the most recent version of a file after you upload a new version
• A template on the page has been updated

Wikipedia:Purge on Wikipedia

Purge clears the page's server cache, and the page is rebuilt. After purging, you may want to try first to refresh the page using your web browser.

Some pages use transclusion to incorporate subpages or templates. If you can't see the transcluded pages properly, purging might help. However purging does not apply new categorization and "what links here" changes from templates; in these cases a null edit is required.

Anyone can request that a purge be performed, including anonymous editors. Issuing the command is not harmful to the operation of the website, but consumes a small amount of additional processing power to rebuild the page.

How to

Basic

From any USApedia page:

1. At the end of the URL in the address bar of your browser, add the text
   ?action=purge
2. Press ↵ Enter or click "Go" to tell the browser to go to that revised URL
3. The page should be refreshed in a short time

Adding a button

You can also add a clickable link, by adding a template, to clear the local version of the page (server cache).

1. Go to the the page you wan to add it.
2. Edit the page and add a Templates at the bottom of the page
3. Save the page; this provides a permanent link on the page for purging. One may also just use preview, click on the link there to get to the purge page.
4. Click on the link it creates (you'll see a blue link called "purge" or "Purge this page's server cache")

All of these templates below will do the same thing. An example of how the button will appear is below each bullet.
