将所有 http/www 重定向到 https://www

Question

I have this code:

RewriteEngine On

RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ https://www.example.com/$1 [L,R=301]

What this does is:

• With http://example.com it redirects to https://www.example.com (this is correct)
• With https://example.com it redirects to https://www.example.com (this is correct)
• But with http://www.example.com it doesn't redirect to https://www.example.com .

Please take note that It needs to be not more than 1 chain. It should redirect to https://www.example.com .

Answer 1

Okay I just fixed it.

this is the updated code

RewriteEngine On

RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^www.example.com [NC]
RewriteRule ^(.*)$ https://www.example.com/$1 [L,R=301]

RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ https://www.example.com/$1 [L,R=301]

I can guarantee that this will all do 301 redirect without more than 1 chain . I hope this helps some developers out there!.

Answer 2

You can avoid hardcoding your host name and do both conditions in a single redirect rule like this:

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