Parse HTTP X-Forwarded-For header
This is a Node.js module available through the npm registry. Installation is done using the npm install command:
$ npm install forwarded
var forwarded = require('forwarded')
var addresses = forwarded(req)
Parse the X-Forwarded-For header from the request. Returns an array of the addresses, including the socket address for the req, in reverse order (i.e. index 0 is the socket address and the last index is the furthest address, typically the end-user).
