|Setting this to true will invalidate all cached pages whenever LocalSettings.php is changed
|Introduced in version:||1.17.0 (r77878)|
|Removed in version:||still in use|
Setting this to true will invalidate all cached pages whenever LocalSettings.php is changed. This is useful so that if you install a new extension, any old pages that were cached before the extension was installed are re-rendered.
On high-traffic wikis, this should be set to false, to avoid the need to check the file modification time, and to avoid the performance impact of unnecessary cache invalidations.
$wgCacheEpoch = max( $wgCacheEpoch, gmdate( 'YmdHis', @filemtime( __FILE__ ) ) );
