301 Old domain with HTTPS to new domain with HTTPS

[waqid]

I am a bit boggled about https to https

we redirected olddomain.com to https://www.newdomain.com, but redirecting https://www.olddomain.com or non-www is not possible. because the certificate does not exist on a level where you are redirecting. only if I setup a new host and add a htaccess file will this work.

What should I do? just redirect the rest and hope for the best?

So i figured out another way. I did a 301 at the registrar level directly to the https. this ensures every version from that domain (http, https, www or non www) all go to the same URL with https without 2 or 3 redirects.

Hello,

Add:

# Canonical https/www

RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} !^www. [NC]
RewriteCond %{HTTP_HOST} ^(.*)$ [NC]
RewriteRule (.*) https://www.%1/$1 [R=301,L]

To the .http access file on your web server
