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)

"""

# 206 Partial Content Response

r = urllib.addinfourl(fp, hdrs, req.get_full_url())

r.code = code

r.msg = msg

return r

def http_error_416(self, req, fp, code, msg, hdrs):

# HTTP's Range Not Satisfiable error

errMsg = "Invalid range"

raise SqlmapConnectionException(errMsg)
