apache 将 http 重定向到 https，将 www 重定向到非 www

Question

basically what i want is redirect al request to use HTTPS instead of http

I have this in my htaccess so far and it worked great: Code:

<IfModule mod_rewrite.c> 
RewriteEngine On 
RewriteCond %{HTTPS} off 
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} 
</ifModule> 

today someone noticed that when going to: http://www.example.com it redirects to and shows an unsecure connection thingie.

My ssl is setup for non www domain: mydomain.com

So i need to make sure all site requests are sent to non www and https: It works fine if i put example.com it redirects to https://example.com

but with www.example.com it goes to htts://www.example.com and shows the error

what do i need to add to my code to redirect www to non www and then to ssl ?

Answer 1

You will have to re-issue your certificate for both www and without www.

If someone connects to your site via a domain name that is not included in your common name, they will receive a warning.

The ssl negociation process happens before any response from the server (in your case, a redirection), so in all cases, your visitors will receive a warning when using a domain that is not in your common name.

Answer 2

You can get what you need from the HTTP_HOST

RewriteEngine On 
RewriteCond %{HTTPS} off 
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.*)$ [NC]
RewriteRule (.*) https://%1%{REQUEST_URI} [L,R=301]

This way it will get the host always without the subdomain.

Answer 3

RewriteEngine On 
RewriteCond %{HTTPS} off
RewriteRule (.*) https://domain.com%{REQUEST_URI} [L,R=301,NC]
RewriteCond %{HTTP_HOST} ^www.domain.com [NC]
RewriteRule (.*) https://domain.com%{REQUEST_URI} [L,R=301,NC]

Answer 4

If you are using CloudFlare's free account then that's the problem. CloudFlare's free account does NOT support SSL Certificates. To continue using CloudFlare's free account with an SSL Certificate just go to the DNS settings in CloudFlare and take the orange cloud off of your domain and off of the cname WWW. That will fix your problem and cause both www and non-www to be redirected to https.

Also be sure to add this code to your .htaccess file:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Then, everything should work!

Answer 5

RewriteEngine On 
RewriteCond %{HTTPS} off 
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.*)$ [NC]
RewriteRule (.*) https://www.%1%{REQUEST_URI} [L,R=301]

Answer 6

Check out this:

RewriteEngine On
RewriteCond %{HTTP_HOST}#%{HTTPS}s ^www\.([^#]+)#(?:off|on(s)) [NC]
RewriteRule ^ http%2://%1%{REQUEST_URI} [R=301,L]
RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]

Answer 7

This will redirect all of your www websites to non-www and secure them if you have completed the CERTBOT for each domain conf file. Put this in /etc/apache2/apache2.conf inside the Directory /www section:

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

There is no need to CERTBOT a www domain after this code is inserted. Just do the domain.com choice. You do not need htaccess files. They can be restricted by the AllowOverride None selection.

Remember to restart apache.
