Answer 1

1. Make a .htaccess file in your root directory.
2. Put this code into it and customize the RewriteRule.

    RewriteEngine On
    RewriteBase /
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^ http://127.0.0.1/dir/index.php [L]

Works perfectly on my localhost.
