Set the Range header for HTTP requests.  The format is specified here:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35.  Note
that web servers are not *required* to support this header.

In [10]: req = urllib2.Request('http://cdimage.debian.org/debian-cd/6.0.2.1/amd64/iso-cd/debian-6.0.2.1-amd64-CD-1.iso',
headers = { 'Range' : 'bytes=0-499' })

In [11]: f = urllib2.urlopen(req)

In [12]: data = f.read()

In [13]: len(data)
Out[13]: 500

In [14]: print f.headers
