Install Joomla in a subdirectory

Question

As some of you may know, Wordpress has an options in settings to allow site installation in a subdirectory, while having the site URL be the main domain. It was something li

Answer 1

I first tried the accepted answer. However, that answer also redirects existing files and folders to the new subdir.

For this reason I used:

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

instead.

I'm aware that this is not the best solution as it doesn't hide the sub directory properly. However, it allows to keep the existing code on that site working.
