Note that apache doesn't run the rewrite-rules just once. It tries applying the rules until the url no longer changes (this makes mod_rewrite extremely powerful). That is why you get the error. The rules are creating a redirect loop.

e.g /cms/test directs to /Cms/index.php/test, which in turn is matches by the second rule, causing it to direct to /App/index.php/Cms/index.php/test, this url get matched again by the second rule, directing it to /App/index.php/App/index.php/Cms/index.php/test etc.

To prevent this loop, add a rewrite-condition:

RewriteEngine On
RewriteRule ^cms     /Cms/index.php/$1 [L]
RewriteCond %{REQUEST_URI} !^/(Cms|App)
RewriteRule ^.*$     /App/index.php/$1 [L]
