Details

This variable is about telling MediaWiki an array of CIDR blocks where any IP address part of the range has to be considered as a Proxy server.

Same as $wgCdnServers , except that MW has no methods to send HTTP PURGE to an origin part of the configured ranges.

If you have individual IP addresses, refer to $wgCdnServers .

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