Could you please explain why i need to ensure that? and how i can ensure
that in my code?

command line curl(*) range seems to work:

Yes, The header was different from the command line tool.
In response to the range request the command line tool gets 206 Partial
Content but pycurl code gets 200 OK response. The content-length field is
also different. I tried-

In the command line:

curl -v -r 0-10 http://cache1.tinyvid.net/otaku/3237ep5-Dragon_Ball_Z.mp4

The code:

import pycurl
import cStringIO
url="http://cache1.tinyvid.net/otaku/3237ep5-Dragon_Ball_Z.mp4"
def test(debug_type, debug_msg):
     if debug_type!=3:
        print "debug(%d): %s" % (debug_type, debug_msg)

c=pycurl.Curl()
c.setopt(pycurl.URL,url)
c.setopt(c.VERBOSE,True)
c.setopt(pycurl.DEBUGFUNCTION, test)
c.setopt(pycurl.FOLLOWLOCATION,0)
c.setopt(pycurl.NOPROGRESS,0)
c.setopt(c.NOBODY, 1)
header = cStringIO.StringIO()
c.setopt(c.HEADERFUNCTION, header.write)
c.setopt(pycurl.RANGE,"0-10")
try:
c.perform()
except pycurl.error,e:
print e

Any idea why they are different?
