How do I host my primary domain from a sub-folder by using the .htaccess file?

By default, the primary domain will use the public_html directory for its files.
Additional domains (addon, subdomains) will use subdirectories inside the root directory.

However, it is possible to host the main domain from a subfolder within the public_html by configuring a redirection in the .htaccess file in the public_html folder, so that the server redirects all requests for the primary domain to that subfolder inside the public_html.

Site visitors won't know that the domain is loading from a sub-folder, which is not added to the URL name.

To perform this operation, the following lines must be added to the .htacces file in the public_html:

#Activate modul Rewrite
RewriteEngine on

#Replace "domeniu.ro" with the desired domain RewriteCond %{HTTP_HOST} ^(www.)?domeniu.ro$

#Replace "subfolder" With the name of the subfolder used.
RewriteCond %{REQUEST_URI} !^/subfolder/

#Do not change these lines
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

#Replace "subfolder" with the name of the subfolder used.
RewriteRule ^(.*)$ /subfolder/$1

#Replace "domeniu.ro" with the desired domain
RewriteCond %{HTTP_HOST} ^(www.)?domeniu.ro$

#Replace "subfolder" with the name of the subfolder used and index.html with the desired default page.
RewriteRule ^(/)?$ subfolder/index.html [L]
