Great for testing your website at proxy location
Great for grabbing a screen shot of your website from proxy location

Examples

vanilla http server

Simple app. If created on heroku, go to https://applicationname.herokuapp.com/twitter.com/

require('http')
  .createServer(require('bfn-proxy')())
  .listen(process.env.PORT || 8080)

express/connect simple

Simple app using middleware, i.e. http://servername.com/ipecho.net/plain

var express = require('express')
var pxy = require('bfn-proxy')()

var app = express()

app.use(pxy)

express/connect advanced

Only allow access from your local server with URI prefix '/pxy', i.e. http://127.0.0.1/pxy/www.bluefidelity.com/

var express = require('express')
var pxy = require('bfn-proxy')()

var app = express()

app.use('/pxy/', function (req, res, next) {
  if (req.connection.remoteAddress !== '127.0.0.1') {
    return next(new Error('Bad authentication data'))
  }
  pxy(req, res)
})
