Handler that enables HTTP Range headers.
Reference: http://stackoverflow.com/questions/1971240/python-seek-on-remote-file
This was extremely simple. The Range header is a HTTP feature to
begin with so all this class does is tell urllib2 that the
"206 Partial Content" response from the HTTP server is what we
expected.
Example:
import urllib2
import byterange
range_handler = range.HTTPRangeHandler()
opener = urllib2.build_opener(range_handler)
# install it
urllib2.install_opener(opener)
# create Request and set Range header
req = urllib2.Request('http://www.python.org/')
req.header['Range'] = 'bytes=30-50'
f = urllib2.urlopen(req)
