2. http://www.example.com -> https.www.example.com (not work)

Above example return url with two http://www.www

https.www.www.example.com

My code

RewriteCond %{HTTP_HOST} !=""
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

What i do wrong?

>Solution :

You can use this redirect to combine http -> https and www redirects into one rule:

# add www and turn on https in a single redirect rule
RewriteCond %{HTTP_HOST} !^www\. [NC,OR]
RewriteCond %{HTTPS} !on
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://www.%1%{REQUEST_URI} [R=302,L,NE]

Once you verify it is working fine, replace R=302 to R=301. Avoid using R=301 (Permanent Redirect) while testing your mod_rewrite rules.

Your rule on the other hand is attempting to maintain same scheme (http or https) after redirect. Your rule is also working for the case when www is missing. You need to use OR between 2 conditions as I have shown in my answer.
