APP_HOST is the url to the server.  Do not add the port to this url, add that to APP_PORT.  Set APP_PORT to whatever port the nodejs app should run on.

CLIENT_HOST is the url to the client.  Add the port to the end if necessary

IIIF_URL can be localhost, as the service is included with DigitalCollections.  Make sure the port listed here is the port that DigitalCollections is running on.
