NAME
    Plack::Middleware::ForwardedHeaders - Use headers from reverse proxy

SYNOPSIS
        use Plack::Builder;
        builder {
            enable 'ForwardedHeaders';
            $app;
        };

DESCRIPTION
    Uses forwarded headers to determine remote IP address and HTTPS status.
    It will adjust the `REMOTE_ADDR', `HTTPS', and `psgi.url_scheme'
    environment items accordingly. The original values are stored in
    `ORIGINAL_REMOTE_ADDR', `ORIGINAL_HTTPS', and
    `original.psgi.url_scheme'.

    WARNING: Enabling this middleware without a reverse proxy or a properly
    configured list of trusted proxies will allow users to spoof their IP
    address.

CONFIGURATION
    trusted
        An IP address or an array reference of IP addresses of trusted
        proxies. If set, the forwarded headers will only be used if the
        request comes from one of the addresses listed as trusted.
