how tell Konqueror to put cash in $TMP?

[Douglas Allan Tutty <dtutty@porchlight.ca>]

I have /tmp on tmpfs and use libpam-tmp so I have per-user $TMP, and
swap is encrypted.

I would like Konquorer (and anything else with a cache) to put the cache
in $TMP.  Is there a way to change where it puts it?

Thanks, Doug.
