$proxyHeader : string

 

List of trusted proxy IP addresses

$trustedProxies : array

$useProxy : bool

As default this setting is disabled - IP address is mostly needed to increase security. HTTP_* are not reliable since can easily be spoofed. It can be enabled just for more flexibility, but if user uses proxy to connect to trusted services it's his/her own risk, only reliable field for IP address is $_SERVER['REMOTE_ADDR'].
