如何从http重定向到https

Question

How to redirect from http to https:

1. redirect http://example.com to https://www.example.com
2. redirect http://www.example.com to https://www.example.com
3. redirect https://example.com to https://www.example.com

Like facebook, google?

Please help me with code in .htaccess or another.

Answer 1

To handle all these 3 redirects in a single rule you can use this code in your DOCUMENT_ROOT/.htaccess file:

RewriteEngine On

RewriteCond %{HTTP:CF-Visitor} '"scheme":"http"' [OR]
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^ https://www.example.com%{REQUEST_URI} [NE,R=301,L]

RewriteCond %{HTTP:CF-Visitor} '"scheme":"http"'
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [NE,R=301,L]

Answer 2

just add below to your .htaccess

RewriteEngine On
RewriteCond %{HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

Answer 3

RewriteEngine On
# ensure www.
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https 
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
