htaccess: redirect to https://subdomain.domain.com

Question

I want to redirect my website to https://subdomain.domain.com in my .htaccess file.

Redirects:

http://subdomain.domain.com => https://subdomain.domain.com

http://www.subdomain.domain.com => https://subdomain.domain.com

https://www.subdomain.domain.com => https://subdomain.domain.com

https://subdomain.domain.com => no redirects

Answer 1

This should do it…

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

Answer 2

First rule redirect all www to https://subdomain.domain.com , second all http to https://subdomain.domain.com

RewriteEngine On

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

RewriteCond %{HTTPS} off
RewriteRule (.*) https://subdomain.domain.com/$1 [R=301,L]
