ka-Map was born to avoid such a kind of problem: once the cache is done 
the client will access only the tiles it needs to see the zoom level 
it's navigating. With the default configuration there will be not a 
second access to raw data.
you can maybe face perfomance problems creating the cache (see precache 
stuff); to avoid this kind of problems see tileindex for mapserver [1]
