See the -T (--temp-dir) option for how to tell rsync to put its temp
file in some other directory.  If the temp dir is on the same file
system as /var/www, rsync will still rename the new file over the top of
the old one (which insures that no one can request a partially-written
file).  If it is on a different file system, rsync will use its
copy_file() routine to copy the tmp file over the destination file.
