NAME
Plack::Middleware::RealIP - Override client IP with header value
provided by proxy/load balancer
SYNOPSIS
enable 'Plack::Middleware::RealIP',
header => 'X-Forwarded-For',
trusted_proxy => [qw(192.168.1.0/24 192.168.2.1)];
DESCRIPTION
Plack::Middleware::RealIP is loose port of the Apache module
mod_remoteip. It overrides "REMOTE_ADDR" with the IP address advertised
in the request header configured with "header".
When multiple, comma delimited IP addresses are listed in the header
value, they are processed from right to left. The first untrusted IP
address found, based on "trusted_proxy", stops the processing and is set
to be "REMOTE_ADDR". The header field is updated to this remaining list
of unconfirmed IP addresses, or if all IP addresses were trusted, this
header is removed from the request altogether.
CONFIGURATION
header
Sets a request header to trust as the client IP, e.g. X-Client-IP
trusted_proxy
A list of IP addresses or subnet blocks which are trusted to provide IP
header.
