+     * The "**" character is syntactic sugar within
+     * TrustedProxy to trust not just any proxy that
+     * connects directly to your server, but also
+     * proxies that connect to those proxies, and all
+     * the way back until you reach the original source
+     * IP. It will mean that $request->getClientIp()
+     * always gets the originating client IP, no matter
+     * how many proxies that client's request has
+     * subsequently passed through.
