Methods

class UnXF

Rack middleware to remove "HTTP_X_FORWARDED_FOR" in the Rack environment and replace "REMOTE_ADDR" with the value of the original client address.

Constants

LOCALHOST

IPv4 localhost addresses (127.0.0.0/8)

LOCALHOST6

IPv6 localhost address (::1/128)

RFC_1918

local LAN addresses described in RFC 1918

Public Class Methods

new (app, trusted = [:RFC_1918, :LOCALHOST, :LOCALHOST6]) source

In your Rack config.ru:

use UnXF

If you do not want to trust any hosts other than "0.6.6.6", you may only specify one host to trust:

use UnXF, "0.6.6.6"

If you want to trust "0.6.6.6" in addition to the default set of hosts:

use UnXF, [ :RFC_1918, :LOCALHOST, "0.6.6.6" ]

Public Instance Methods

on_broken_addr (env, xff_str) source

Our default action on a broken address is to just fall back to calling the app without modifying the env

on_untrusted_addr (env, xff_str) source

Our default action on an untrusted address is to just fall back to calling the app without modifying the env

unxf! (env) source

returns nil on success and a Rack response triplet on failure This allows existing applications to use UnXF without putting it into the middleware stack (to avoid increasing stack depth and GC time)
