Paul,
One thing to do first: read the manual for the proxy server and see
if it has a switch or an environment variable to set where it expects
its "stuff", and use that instead of all this rigamarole, if not...

No, in general.
Well, you don't have to really reinstall -- what you have to do is
save the partitions in question, (on tape or on a slice or device
you're not messing with), then run disklabel -e, repartition the
slice in question, then newfs and restore the partitions whose
offsets or sizes have changed. If you don't understand that, don't
try it.
Instead of that, try this:
Let's suppose it is writing to a file /var/stuff/foo.cache. You
would like it to be writing to /usr/stuff/foo.cache.
Step one: kill the software. If this is a busy machine, maybe
go to single user mode.
Step two: copy everything so that /usr/stuff/* is just like
/var/stuff/*
one way:
cd /var
tar cpf /tmp/stuff.tar stuff
cd /usr
tar xvpf /tmp/stuff.tar
rm /tmp/stuff.tar
[the tar can be simplified:
(cd /var; tar cpf - stuff)|(cd /usr; tar xvpf - )]
Some men use cp -R, but I don't like innovation.
Step three: Whack the old directory
rm -r /var/stuff
(or, for the timid, mv /var/stuff /var/oldstuff)
Step four: Make symbolic link:
cd /var
ln -s /usr/stuff stuff
Step Five: restart the software.
Note: this doesn't need to be on /usr, necessarily.
Another method is to hack the source (possibly only a change in a Makefile),
rebuild and reinstall the software in question.
