This [link](www.imlovingdogs.com) is pointing to my home directory. I want my users to see `~/home/prototype.php` page when they come to my site.
To achieve this, I have set following in my .htaccess file of that directory:

    DirectoryIndex /home/prototype.php
    # BEGIN WordPress
        <IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteBase /
        RewriteRule ^index\.php$ - [L]
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteRule . /index.php [L]
        </IfModule>
        # END WordPress

 There is a form which they need to fill and submit. The redirection of this form is set to `www.imlovingdogs.com/index.php` i.e. the main index.php page where wordpress starts loading other required files. But this index.php doesn't work! How can I achieve this kind of flow for  my users?
