Personas 3.0: How to made a Relative url for a HTML Viewer?

Hi Personas 3.0 experts,

We had developed app UIs on development system (dev-sys), where UI shows a HTML Viewer object using a full url (domain, port are set to dev- sys). After we move the app to quality system (Q-sys), the HTML Viewer is shown with link to dev-sys. I removed the root url, just let it have "/sap/...", but it won't show the HTML obj.

Questions:

1. Is it corect to remove the domain and port in url to make it a relative url?

2. Does it still need Whitelist on Q-system?

Br,
