htaccess to display subfolder as the domain name

inside the public_html directory, we want to use the subfolder for example named 'mysubfolder' but in the url shown as http://www.mydomain.com or http://mydomain.com instead of http://www.mydomain.com/mysubfolder.

Below is the .htaccess code to be put in the public_html directory.

RewriteEngine on

RewriteCond %{HTTP_HOST} ^mydomain.com$ [OR]

RewriteCond %{HTTP_HOST} ^www.mydomain.com$

RewriteCond %{REQUEST_URI} !^/mysubfolder/

RewriteRule ^(.*)$ mysubfolder/$1 [L]
