htaccess: Redirect All domains (https and http) to new domain

Question

My current domain is a free https.

I add new domains as parked domains Alias (in DirectAdmin).

So for the new domain to use https, I need to disable https for the old domains.

Now I want to transfer all the old domains to the new domain with https.

I think the solution is that https should be disabled for all domains except the new domain, then the address will be transferred to the new domain

Answer 1

You can force https like so:

RewriteEngine On 
RewriteCond %{HTTPS} off 
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

That should go to your .htaccess to your root folder

Answer 2

You can use this :

RewriteEngine on

RewriteCond %{HTTP_HOST} !^(www\.)?newdomain\.com$ [NC]
RewriteRule (.*) https://www.newdomain.com/$1 [L,R=301]

This will redirect all parked domains (pointing to your document root) to your new domain url .

The RewriteCondition above makes sure you don't redirect newdoman to itself otherwise the rule would cause a redirect loop error.
