  • $ip - The IP address of the proxy.
  • $trusted - A bool indicating the IP is or isn't trusted.

Modifies the behavior of ProxyLookup::isTrustedProxy; this is more or less the dynamic equivalent of setting $wgCdnServers . It mainly means that when a request coming from this IP tells (via the X-Forwarded-For header) that the real source of the request is some other IP, MediaWiki will trust that claim.
