mod rewrite - .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!

Answer 1

I would put this into the domain's root directory:

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