Deprecated. Setting first appeared in 1.4.1, but was commented out in DefaultSettings.php . Set to false from 1.9.0. Replaced by $wgHTCPMulticastRouting in MediaWiki 1.20 and $wgHTCPRouting in MediaWiki 1.22 and subsequent versions.

HTCP is a method of purging entries from the Squid cache that can use multicast and udp which is faster then opening an http connection to every squid server.

The $wgHTCPMulticastAddress variable is deprecated as of MediaWiki 1.20.0 but is still recognized by being copied to the new one in includes/Setup.php :

// $wgHTCPMulticastRouting got renamed to $wgHTCPRouting in MediaWiki 1.22
// ensure back compatibility.
if ( !$wgHTCPRouting && $wgHTCPMulticastRouting ) {
        $wgHTCPRouting = $wgHTCPMulticastRouting;

// Initialize $wgHTCPRouting from backwards-compatible settings that comes from pre 1.20 version.
if ( !$wgHTCPRouting && $wgHTCPMulticastAddress ) {
        $wgHTCPRouting = array(
                '' => array(
                        'host' => $wgHTCPMulticastAddress,
                        'port' => $wgHTCPPort,
