Should be simple enough. Implement
HttpServletRequestListener
 and store the current request in a ThreadLocal (calls to onRequestStart aren’t serialized in the same way as business calls to the Application object are). So your application would include:

    private static final ThreadLocal<HttpServletRequest> tlRequest =
        new ThreadLocal<HttpServletRequest>();

    @Override
    public void onRequestStart(HttpServletRequest req, HttpServletResponse resp) {
        tlRequest.set(req);
    }

    @Override
    public void onRequestEnd(HttpServletRequest req, HttpServletResponse resp) {
        tlRequest.remove();
    }

Now in your init() method grab the request and call
getRequestURL()
,
getServerName()
, or something similar to get the URL that was used to access the application. Then you can call setTheme() from there to set the correct theme.
