Konquorer Cache

I am basically doing a hybrid cd/hd/floppy install

Standard knoppix 3.1 with all system files kernel, loader, basically the entire knoppix distro run off cd. Cofnig info is stored on the floppy to make a hardened kiosk internet system, the problem is my site requires all internet usage and files to be stored, now I have a 10 gig hd on all the machines and I need to find the path to the cache and somehow symlink the cache dir to the hd, if somebody could point out the location of the cache dir as well as the rpocess for unlinking it from the file system and mounting the hd there instead I would greatly appreciate it.
