Make it so that the index.html can specify the public path

    <script type="application/javascript">
        window.resourceBasePath = '/path/to/scripts/on/server/';
    </script>

Then add in the code support that.

The nginx config could possible then use a substitution filter to update the public path when serving the index.html

This would allow the UI to be served from dynamic paths on a server.
