Have thought about it many times over the years but FTP is a bit tricky
to cache.. there is a whole lot of state involved on the server and no
standard path structure definition. A striking example is that / or ..
does not have any special meaning in FTP.

In theory one could use PWD to verify the state, but there is
unfortunately servers which do not include the full location state in
their PWD response, sometimes omitting things small like partition/drive
while still allowing the client to change partition/drive either using
CWD <magic partition name like c:> or SITE commands.
