Use correct port in with-zones example

[tomaswitek]

According to proxy rules the blog app should start on port 5000:

{
  "rules": [
    {"pathname": "/blog", "method":["GET", "POST", "OPTIONS"], "dest": "http://localhost:5000"},
    {"pathname": "/**", "dest": "http://localhost:4000"}
  ]
}

Hi, I am having this error after installing with-zones example.

Home and Blog are running in the correct port, but proxy fails.

Is this working for you?

Thanks

@jmaguirrei related to you being on a node version under 9. Will be fixed when https://github.com/zeit/micro-proxy/pull/19 lands

@timneutkens Thanks, I upgraded to node v9.5.0, deployed the example to zeit/now and seems to work ok !

I added this in all package.json (and log process.version to confirm is v9.5.0):
"engines": { "node": "9.5.0" },

I am planning to do this in production, is there any downside with this approach?
Link, prefetch, routing should be OK?
