# This extention allows for the easy implementation of keeping a page
# uncached, to use it you can either call the purgePage() function
# from another extention or add the following tags to you wiki page:
#   <purge/>
# To activate the extension, include it from your LocalSettings.php
# with: include("extensions/purgePage.php");
 
$wgExtensionFunctions[] = "wfPurge";
 
function wfPurge() {
	global $wgParser;
	# register the extension with the WikiText parser
	# the first parameter is the name of the new tag.
	# In this case it defines the tag <purge></purge>
	# the second parameter is the callback function for
	# processing the text between the tags
	$wgParser->setHook( "purge", "purgePage" );
}
 
# The callback function for perfoming the purge
