import urllib2_files
import urllib2
u = urllib2.urlopen('http://site.com/path' [, data])
 
data can be a mapping object or a sequence of two-elements tuples
(like in original urllib2.urlopen())
varname still need to be a string and
value can be string of a file object
eg:
  ((varname, value),
   (varname2, value),
  )
  or
  { name:  value,
    name2: value2
  }
