NewestFile allows a web client to request a file, such as a program or image, from
the host CR1000. If a wildcard (*) is included in the expression, the most recent
in a set of files whose names match the expression is returned. For instance, a
web page may be designed to show the newest image taken by a camera attached
to the CR1000. NewestFile takes the form:
http://192.168.13.154/command=NewestFile&expr=drive:filename.ex
t
Where filename can be a wildcard (*).
NewestFile requires a minimum .csipasswd access level of 3 (read only) for all
files except program files. Program files require access level 1 (all access
allowed).
