For the latest ISPConfig 3 installation, suppose I have 2 domains: primary.com and alias.com and do: Domain: alias.com Parent Website: primary.com Redirect Type: no redirect Redirect Path: <empty> Auto-Subdomain: *. SEO Redirect: No redirect Don't add to Let's Encrypt certificate: [ ] unchecked Active: [x] checked Then, in a browser, my test cases include: https://primary.com, https://www.primary.com http://primary.com, http://www.primary.com https://alias.com, https://www.alias.com http://alias.com, http://www.alias.com For each of the tests, the browser address bar shows the same URL I've entered. I note that no automatic http -> https redirection happens. For all of the above cases, I want the browser URL to change to https://primary.com. I've tried changing the Redirect Type to R=301,L. But, the browser URL does not change from alias.com to primary.com. The www removal does happen. I perform the tests only after I verify that the primary.com.vhost file has been updated. Can you explicitly state for each of the fields above what I should put to get the desired behavior that the browser URL should always change to https://primary.com, regardless of what is entered? Or, if other steps are needed, please share. Many thanks!
