+/**
+ * Routing configuration for HTCP multicast purging. Add elements here to
+ * enable HTCP and determine which purges are sent where. If set to an empty
+ * array, HTCP is disabled.
+ *
+ * Each key in this array is a regular expression to match against the purged
+ * URL, or an empty string to match all URLs. The purged URL is matched against
+ * the regexes in the order specified, and the first rule whose regex matches
+ * is used.
+ *
+ * Example configuration to send purges for upload.wikimedia.org to one
+ * multicast group and all other purges to another:
+ * $wgHTCPMulticastRouting = array(
+ * '|^https?://upload\.wikimedia\.org|' => array(
+ * 'host' => '239.128.0.113',
+ * 'port' => 4827,
+ * ),
+ * '' => array(
+ * 'host' => '239.128.0.112',
+ * 'port' => 4827,
+ * ),
+ * );
+ *
+ * @see $wgHTCPMulticastTTL
