Redirect all traffic but "beta" sub-domain to Splash screen (mod_rewrite) - zend-framework

Question

I'd like to redirect all my traffic to my root domain, the root domain being a Splash screen. I'd like to do this ONLY when the %{HTTP_HOST} is not beta.example.(com|es|fr).
So I've tried the following in my .htaccess file, with no luck... (infinite loop... I guess it's not getting the REQUEST_URI condition, but cannot figure out why?? I've tried almost everything)
RewriteCond %{HTTP_HOST} !^beta\.example\.com$
RewriteCond %{HTTP_HOST} !^beta\.example\.es$
RewriteCond %{HTTP_HOST} !^beta\.example\.fr$
RewriteCond %{REQUEST_URI} !^/?$
RewriteRule ^.*$ / [NC,L,R=302]
At that point, I should have all my traffic but "beta" sub-domain redirected to the root domain. So now I'd like to Rewrite "backstage" the root domain with my Splash screen, following in the .htaccess file:
RewriteCond %{HTTP_HOST} !^beta\.example\.com$
RewriteCond %{HTTP_HOST} !^beta\.example\.es$
RewriteCond %{HTTP_HOST} !^beta\.example\.fr$
RewriteRule !\.(js|ico|txt|gif|jpg|png|css)$ splash.phtml [NC,L]
Note: I'm using the Zend Framework, so these rules are following in the .htaccess file:
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]
I must say, I'm stuck.
thx in advance

This line from Zend is going to screw you up for sure.
RewriteRule ^.*$ index.php [NC,L]
You need to put your directives above this, if not above all of the Zend stuff. If I'm understanding you correctly, try this:
RewriteCond "%{HTTP_HOST}" "!^beta\.example\.(com|es|fr)$" [NC]
RewriteCond "%{REQUEST_URI}" "!\.(js|ico|txt|gif|jpg|png|css)$" [NC]
RewriteRule ".*" "/splash.phtml" [R=302,L]
