Description

This template purges the server cache for a page. Normally computer servers cache results for speed, not checking every time whether a page has changed. Purging the page tells the server to check the page anyway. This is useful in certain circumstances, including:

• where <option>…</option> tags are used (e.g. any of the pseudo-random selection templates)
• any page with DPL serving out-of-date results (e.g. UN:VFH)

A fuller explanation can be found at wikipedia:WP:PURGE.

Usage

1. {{P}}
2. {{P|what text}}
3. {{P|page=which page}}
4. {{P|page=which page|what text}}

Examples

Purge the current page:

{{P}}

Purge the page with different text:

{{P|Refresh server cache}}

Purge UN:VFD from a header page:

{{P|page=UN:VFD|Refresh UN:VFD}}

History

Template:Open and purge redirects here.

PuppyOnTheRadio made {{Open and purge}}, which allowed for opening a different page. In the interest of unity, that template and its alias {{P}} now redirect here. The syntax has changed slightly.

Old syntax for {{Open and purge}}:

1. {{P}}
2. {{P|2=what text}}
3. {{P|which page}}
4. {{P|which page|what text}}

New syntax for this template:

1. {{P}}
2. {{P|what text}}
3. {{P|page=which page}}
4. {{P|page=which page|what text}}
