HTTP proxy (CDN) settings: $wgCdnServersNoPurge
Same as $wgCdnServers , except no HTTP purges will be sent and CIDR ranges are accepted
Introduced in version:1.34.0 (Gerrit change 387877; git #f9f8dff4)
Removed in version:still in use
Allowed values:(IPv4 & IPv6 addresses and/or Classless Inter-Domain Routing (CIDR) blocks)
Default value:[]



This variable is about telling MediaWiki an array of CIDR blocks or individual IP addresses where any IP address that is part of the range has to be considered as a Proxy server. This means that X-Forward-For headers will be respected for requests from IP addresses or ranges on this list.

Same as $wgCdnServers , except that MW does not send PURGE requests to clear cache. You can use this setting for proxy servers that do not cache content or are purged by a different means such as Purged.

All documentation in Manual:$wgCdnServers#Configuration example with Varnish is valid, but with difference described below.

// In LocalSettings.php
$wgUseCdn = true;
$wgCdnServersNoPurge = [];
$wgCdnServersNoPurge[] = "";
