<VirtualHost *:80>

    ServerAlias *.datingjapan.co
    DocumentRoot /var/www/html/datingjapan.co

    RewriteEngine on

    RewriteCond %{HTTP_HOST} !^www\. [NC]
    RewriteRule ^(.*) http://www.%{HTTP_HOST}$1 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-l
    RewriteRule ^(.*)$ /index.php?/$1 [L,QSA]
