Redirect to https for specific domain?

Question

htaccess

Need to redirect to https for a specific domain.
We have apache and these Googled rules:
RewriteCond %{HTTP_HOST} ^example\.com [NC]
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
We get "A cyclic redirect was detected on this page" ((
Tell me how to fix it.

Answer 1

SSL was configured incorrectly, causing %{HTTPS} to always show off.
