[htaccess] Redirect primary domain from http to https but exclude all subdomains

[slax]

Hi

I want to redirect my primary domain to https (http://www.website.com to https://www.website.com) and exclude all sub domains. (http://xyz.website.com to remain as http://xyz.website.com)

I have been on google for too long and couldnt find the right solution, please help

My .htaccess file

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

[pqt]

Will it only pickup WWW or should it work without it?

WWW is a sub-domain by definition so I'm not sure what you're requesting.

thanks for the reply

we have multiple sub domains around 30+, which are not supposed to be https ... they should be only http

by enforcing these commands in .htaccess these subdomains are not working

[pqt]

RewriteCond %{HTTP_HOST} !^$
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301]

Let's give this a shot. This will redirect domain.com to www.domain.com and then to https://www.domain.com.

if www.domain.com is already found, it will redirect that to HTTPS. My URL rewrites are a little rusty since I use Laravel a lot these days and all of my subdomains are SSL so I don't have to do much with htaccess lately
