But, see the followint testings for my case:

werner_at_debian:~$ curl -r 200-202 localhost -v 1> /dev/null
[snip]
< HTTP/1.1 416 Requested Range Not Satisfiable
[snip]

werner_at_debian:~$ echo $?
0

In the above case, the rquested range is completely out of the range.
Why curl still return will 0?

While for a local file, curl will return 36 if the rquested range is
completely out of the range, see the following:

werner_at_debian:~$ echo "hello world" > fnord
werner_at_debian:~$ curl -r 50-100 file://$PWD/fnord
curl: (36) failed to resume file:// transfer
werner_at_debian:~$ echo $?
36

In addition, I've posted another thread on this list with the name
"Requested range is entirely out of the file, but curl still return
with exit status of 0." for this issue.
