In Voila, Redirecting to other notebook or static file

We are using Voila to translate notebooks into standalone web apps. And have a requirement to redirect the user to another resource (another notebook or static HTML file) based on certain condition.
Have had a look at capabilities of TEMPLATEs in Voila but even after placing the target files under Voila is looking for such files under /voila/files and fails.
Any related info will be very helpful.
