I have my domain (http://www.foobar.com, for example) and my website talks about technology. I want to have another website (with other content, not about technology) inside of it (http://www.foobar.com/loremipsum). I can find http://www.foobar.com in Google Search, but http://www.foobar.com/loremipsum no ... What should I do to index this website? Thank you.

update

My main site (http://www.foobar.com/, a WordPress installation) has an .httaccess:

# 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

Does it affect the index of http://www.foobar.com/loremipsum ? Thank you.
