How to redirect to Coming Soon template I want to redirect http://example.com to coming-soon.html template, but not index.html.

Possible to do it in route settings?
If you are trying to cover the site from the public while working on it live, i personally would name my coming soon template file 503.html

Then in the General Settings section of the control panel, switch System Status off.

That way so long as you are logged in, you can access the site as normal but anyone else visiting your site will see the contents of the 503.html template.
