You need to block all access to local port 80, in order to avoid the
looping problem.

eg.

ipfwadm -I reject -P tcp -S 127.0.0.1/32 -D 127.0.0.1/32 80
ipfwadm -I reject -P tcp -S 127.0.0.1/32 -D cache.server/32 80
ipfwadm -I reject -P tcp -S cache.server/32 -D 127.0.0.1/32 80
ipfwadm -I reject -P tcp -S cache.server/32 -D cache.server/32 80

Should do the trick.

Also, your using 2.0.30? The transparent port redirection is
broken in this version. Is there a new patch?
