Redirected landing page shows static data

When visitors use http://www.ross.no they are redirected to the WordPress site in subdirectory using this in .htaccess:

# BEGIN WordPress

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /communicate/
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /communicate/index.php [L]
</IfModule>

# END WordPress

The redirect works as expected, except I’ve noticed that the data displayed for the redirected visitors is older/not (about 10 days since last update) updated as is the case when using direct URI.

Example:

http://www.ross.no -> shows older data
http://www.ross.no/communicate -> shows continuously updated data

I don’t know how to remedy this, as I am unable to find out how this seemingly static page is made possible, and how often it’s updated and by what.
