Apache2使用ssl重定向到另一个域

Question

I have a no clue why this fails. I just want to redirect all domain to www.maindomain.com and also http to https , what am i missing?

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

# redirect without www to www
RewriteCond %{http_host} ^maindomain.com [nc]
RewriteRule ^(.*)$ https://www.maindomain.com  [r=301,nc]

# redirect another domain to www.maindomain.com    
RewriteCond %{HTTPS} off # this i was missing 
RewriteCond %{HTTP_HOST} ^(www\.)?anotherdomain.com [NC]
RewriteRule ^(.*)$ https://www.maindomain.com [R=301,L]

1. http://maindomain.com to https:/www.maindomain.com/ works
2. http://anotherdomain.com to https:/www.maindomain.com/ works
3. https://anotherdomain.com to https:/www.maindomain.com/ fails

Answer 1

The Http to Https redirection for Another domain failed because Your Rule is missing the following line :

RewriteCond %{HTTPS} off

Try :

# redirect another domain to www.maindomain.com    

RewriteCond %{HTTPS} off

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

Answer 2

You can try this:

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

Just copy and paste the above code in .htaccess file then the whole website will be redirected to “https” when the browser is opened in “http” mode. The browser just get redirected using url rewriting in .htaccess.
