Apache 2.4.10 on SLES 12. I am trying to redirect a subdomain address from http to https. So when a user forgets to use https they will still land on the correct page. I tried using:

 

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(sub1|sub2|sub3)\. [NC]
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

 

this does not redirect to https. Instead you land at the http site. What in those statements are not correct? I have tried using just 1 subdomain with the same results
