.htaccess redirect subfolder to HTTPS

Question

I'm trying to write a RewriteRule for my .htaccess file. Specifically, whenever a user accesses a specific subdirectory, I would like it to Rewrite to force an HTTPS connection.

For example, whenever someone accesses: http://www.mydomain.com/subdirectory (and any other sub-directories of that "subdirectory").

I'd like it to rewrite to https://www.mydomain.com/subdirectory

I've tried the following, but it appears to create a loop:

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.mydomain.com/subdirectory/$1 [R=301,L]

Also, this .htaccess file is placed in the root of my domain.

Any ideas on how to modify my RewriteRule?

Many Thanks!

Use this if you don't want the address bar to show the subfolder. It will redirect yourdomain.com to yourdomain.com/subfolder but will look like you are still on yourdomain.com

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www.)?yourprimarydomain.com$
RewriteCond %{REQUEST_URI} !^/subfolder/
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /subfolder/$1
RewriteCond %{HTTP_HOST} ^(www.)?yourmaindomain.com$ 
RewriteRule ^(/)?$ subfolder/index.php [L]
