HTTP to HTTPS and 301 redirect chains on Magento

Question

We have successfully moved from HTTP to HTTPS , and now got some redirect chains. We want to do the following, directly:

1. From http ://domain.tld to https ://www.domain.tld

2. From http ://domain.tld/subdir/ to https ://www.domain.tld/subdir/

Right now, www is added first, then again 301 to HTTPS , like this:

1. http ://domain.tld => http ://www.domain.tld => https ://www.domain.tld

2. http ://domain.tld/subdir/ => http ://www.domain.tld/subdir/ => https ://www.domain.tld/subdir/

Also, if possible, all the other domains on the server (Magento stores), should not be able to use HTTPS, and should be redirected back to HTTPS only.

Thanks,

You can combine both http->https and non-www->www rules in one single 301 redirect rule like this:

# // REDIRECT main domain to HTTPS and add www //
RewriteCond %{HTTP_HOST} !^(?!www\.)[^.]+\.domain\.tld$ [NC]
RewriteCond %{HTTP_HOST} ^domain\.tld$ [NC,OR]
RewriteCond %{HTTPS} off
RewriteRule ^ https://www.domain.tld%{REQUEST_URI} [R=301,L,NE]

# redirect sub domains to non http
RewriteCond %{HTTP_HOST} ^(?!www\.)[^.]+\.domain\.tld$ [NC]
RewriteCond %{HTTPS} on
RewriteRule ^ http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L,NE]
