Domain alias for https

Server Config
1

I have a domain alias set up for a subdomain also but need the same subdomain to work with https.

Here’s what I have in .htaccess to make the http alias work:

Options +FollowSymlinks
RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} !^dev.mysite.com.au$
RewriteCond %{REQUEST_URI} !
RewriteRule ^(.*)$ $1

Any suggestions please?
