http to https using htaccess file

[factoring]

Hi,

I am trying to get my admin folder in https. I have tried several different techniques including the following:

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

This makes my homepage go to my admin folder and makes my admin folder do this: admin/admin/index.php.

I am lost at this point.

Thanks

Andrew
