• example.

Answer 1

You can use the following rule to redierct non-www or www to https://www in just one redirection

#redirect http non-www to https://www
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$
RewriteRule (.*) https://www.example.com/$1 [R=301,L]
#redirect https non-www to www
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^example\.com$
RewriteRule (.*) https://www.example.com/$1 [R=301,L]

Clear your browser's cache before testing this rule.

Answer 2

This is the only way it works for me - with !on instead of off and with %{ENV:HTTPS} instead of %{HTTPS}:

  #non-www. http to www. https
  RewriteCond %{ENV:HTTPS} !on
  RewriteCond %{HTTP_HOST} ^(www\.)?yourdomain\.com$
  RewriteRule (.*) https://www.yourdomain.com/$1 [R=301,L]

  #non-www. https to www. https
  RewriteCond %{ENV:HTTPS} on
  RewriteCond %{HTTP_HOST} ^yourdomain\.com$
  RewriteRule (.*) https://www.yourdomain.com/$1 [R=301,L]

#First rewrite any request to the wrong domain to use the correct one (i.e. www.)
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

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