This is a piece of code that I am rolling:

Code:

<IfModule mod_rewrite.c>

# handle domain root and skip subfolders
RewriteCond %{HTTP_HOST} ci.domain.com
RewriteCond %{REQUEST_URI} !^/ci
RewriteCond %{REQUEST_URI} \..+$
RewriteRule ^(.*)$ ci/$1 [L]

# handle files in subfolders
RewriteCond %{HTTP_HOST} ci.domain.com
RewriteCond %{REQUEST_URI} !^/ci
RewriteRule ^(.*)$ ci/$1/ [L]
</IfModule>
