Req Ips

<h3 id='req.ips'>req.ips</h3>

When "trust proxy" is true, parse the "X-Forwarded-For" ip address list and return an array, otherwise an empty array is returned.

For example if the value were "client, proxy1, proxy2" you would receive the array ["client", "proxy1", "proxy2"] where "proxy2" is the furthest down-stream.
