Force non-www and https via htaccess

Question

I\'m trying to force a user to be redirected to the non-www website, and, force https.

I\'ve got this which sort of work, but doesn\'t force https, when http is ente

Answer 1

Based on Gumbo's comment : "the TLS/SSL connection is established and certificate is validated before it is handed down to HTTP and the HTTP redirection takes place" I gave this a try (which seems to work):

RewriteEngine On 
RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://www.blahblah.com/$1 [R,L]

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

please tell me if there is something wrong with this approach.
