.htaccess redirect www to non-www with SSL/HTTPS

I've got several domains operating under a single .htaccess file, each having an SSL certificate.

I need to force a https prefix on every domain while also ensuring www versions redirect to no-www ones.

Below is my code; it doesn't work:

RewriteCond %{HTTP_HOST} ^www.%{HTTP_HOST}
RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI}/$1 [R=301,L]

What I want to achieve is to: redirect something like https://www.example.com to https://example.com.

What am I doing wrong and how can I achieve it?

www to non www with https

RewriteEngine on

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

RewriteCond %{ENV:HTTPS} !on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Ref: Apache redirect www to non-www and HTTP to HTTPS

http://example.com

http://www.example.com

https://www.example.com

to

https://example.com

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]

If instead of example.com you want the default URL to be www.example.com, then simply change the third and the fifth lines:

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

Your condition will never be true, because its like "if (a == a + b)".

I'd try the following:

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

This will capture "google.com" from "www.google.com" into %1, the rest in $1 and after that combining the 2, when HTTP_HOST starts with www (with or without https).

To enforce non-www and https in a single request, you can use the following Rule in your htaccess :

RewriteEngine on

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

This redirects http://www.example.com/ or https://www.example.com/ to ssl non-www https://example.com/ .

I am using R Temp Redirect flag for testing purpose and to avoid browser caching. If you want to make the redirect permanent , just change the R flag to R=301 .
