.htaccess redirect both naked http and https to www https

问题

I have similar issue on one of my domains. I have SSL cert installed both for naked and www-domain.

Now, however I want to redirect both naked http://domain.com and https://domain.com to https://www.domain.com.

I have this rules in my .htaccess, but it covers redirect when you visit site explicitly with https://domain.com, but, when visiting http://domain.com, it redirects to http://www.domain.com instead https://www.domain.com.

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

回答1:

You should replace your existing rule with this rule:

RewriteEngine On

# add www and convert http to https
RewriteCond %{HTTP_HOST} !^www\. [NC,OR]
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://www.%1%{REQUEST_URI} [R=301,L,NE]

Keep this rule right below RewriteEngine On line and clear your browser cache before testing.

I personally would lay it out like this, this will force WWW and HTTPs for everything.

RewriteEngine On

#Force WWW on everything
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

#Force HTTPS on everything
RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]
