memoizeHost option not working

[simondutertre]

Hi,

There seems to be an issue with container.options.memoizedHost in resolveProxyHost.js line 8, not being set anywhere. ( while container.options.memoizeHost is correctly set )

See the following, that should not call getHost on every request right ?

const express = require('express')
const proxy = require('express-http-proxy')

const app1 = express()
const app2 = express()

function getHost() { 
  console.log("getting host");
  return "localhost:8002"
}

app1.use(proxy(getHost, {
  memoizeHost: true // explicitely pass param, but same behavior without
}))

app1.get('/')
app2.get('/', (req, res) => res.send('proxied'))

app1.listen(8001)
app2.listen(8002)

Can you confirm this ?

Thank you
