How do I force htaccess to load https?

[ZORANVEDEK]

I have tried multiple ways to  get this to  work,  I have placed the code above the commented lines, below the commented lines, inside the commented lines, all I get when I do so is a 404.  This is driving me nuts...

...I know it can't be this difficult to  force a secure connection on Prestashop, so I've got to  be missing something obvious here. Where should I put this code inside of the .htaccess file in order to  get this site secure while at the same time not completely shutting down  Prestashop?

 

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

Okay  I got it working by  forcing Prestashop to regenerate the file,  and then adding my  code. 

...still  not showing as secure,  but that's an entire other issue.
